note for the short delayed replication Basically we will have either or not a matrice of error for temperature and humidity for each point. While we are reading the error_data_index that is describing the index of the point : If we have 255 in the value of the error_data_index, that means there is no errors, we will put 0 for the shor delayed replication factor (meaning we skip the other descriptors bellow)
if we a number (corresponding to the current index) we will put 1 and then the 6 following descriptors will be replicated meaning there is actually some error for that particular point

Antoine presented GHG and CO, but work is still in progress on feedback received during last meeting.
@amilan17 will try to set up mtg for 15 May week.

[antoinemerle]

TWV review

(Marijana) asked for clarifications on several elements; The "in bounds check" might fit somewhere else, e.g. significance table [..?..] [ACTION] Antoine double check how many fields for "Satellite instruments" are needed and add notes;

• Add explaination to why do we have 3 times sat identification
• "in bounds check" : Will add a note in colomn D
• "in bounds first guess chedk" : Will add a note in colomn D

(Sergio) questions about pressures and the relationship to air temperature

• Antoine changed the sequence after the discussion with the EUM scientists. only 101 pressure not layers, no need to add a descriptor number layer because the pressure is there for that

---

CLD review

(Antoine) everything is the same up to as TWV until atmospheric profile
(Marjana) Add a significance on the replications of the 2 n_cld to explicit explain what those 2 level correspond too , Antoine will get close to the EUM scientist to find that info and if needed will create a new code table for that one

• Antoine : I could have use class 10 but one was even better 0 20 016 : Pressure at top of cloud with exactly the same scale ref and width as 07
• : add also CLoud phase 0 20 056 in front of the ice/liquid water path to add more information to what type of mass content we are getting.

---

SFC overview

(Sibylle) Pressure should be from category 10, not cat 07, because this is the measurement of the pressure. Cat 07 is to indicate pressure level at a location and here it's not the location, but the measurement;

• Antoine change Pressure code from category 07 to 10 : new code is 0 10 004
• Antoine also move the vertical significance in order to save some bits in the sequence

[amilan17]

https://github.com/wmo-im/CCT/wiki/16.May.2023.satellite.issues/ notes:
Antoine provided an overview of recent changes based on feedback and described in comment above.

@antoinemerle actions:

• add descriptors for 0 15 21 Integrated mass density that indicates the pressure layer for GHG[?]
• update first order statistic code
• change name of 3 10 096 from "temperature" to "pressure"
• will try to provide BUFR sample data for the entries discussed so far before 6 June; noting that Sibylle will only be able to validate in July;
• Sergio will also try to validate before and after his June holidays;

[antoinemerle]

Following the meeting of 16/05/2023 :

Hi @marijanacrepulja and @amilan17 : I updated the proposition according to the presentation I made yesterday.
You can now see in the current status the correction applied.

[marijanacrepulja]

Hi @antoinemerle and @SimonElliottEUM

I had a chat with scientist and it would be beneficial to have following descriptors in the templates for O3, CO, SO2:

• Information about cloud cover, descriptor 020010
• Information about cloud top height, descriptor 020016
• Information about surface type/emissivity, descriptor 013040
• The pressure values (in Pa) at the layer boundaries
• Averaging kernels informations, descriptors 015043, 015044 and related pressure 010004

We would appreciate if you can add the pressure [Pa] of the plume alitude in addition to 0 07 XXA 'Height of the plume' for SO2 BUFR template.

Many thanks

[antoinemerle]

Hi @marijanacrepulja,

Just to let you know that I asked those questions to our scientists, and I am waiting their feedback.
I am going to update the sequences accordingly to what they can provide to us.

Only one quick question concerning the last bullet point :

Averaging kernels informations, descriptors 015043, 015044 and related pressure 010004
Can you describe what you are excepting there exactly ? I am 100% sure that I understood your request.

Thanks for your feedback and review, @marijanacrepulja !

Best,

[marijanacrepulja]

Hi @antoinemerle and @SimonElliottEUM

Many thanks for feedback.

As for averaging kernels and related pressure, we would need as described below:

015043      numberOfAveragingKernelLayers
102000      102000 Replicate 2 descriptors     
031001      delayedDescriptorReplicationFactor  
010004      nonCoordinatePressure   
015044      averagingKernelValue   

[antoinemerle]

Hi @marijanacrepulja ,

On GHG

• I updated GHG according to your comments

on O3, CO and SO2 :

In the case of IASI-NG, unlike IASI, the products are multiple files and not just one, so not all the variables are present in all the products. Unfortunately we don't have what you request in the given product, however it can be find in :

• Information about cloud cover : % coverage of cloud : Available in IAS-02-CLD
• Information about cloud top height : Pressure at cloud top : Available in IAS-02-CLD
• Information about surface type : type of surface (land, sea, ice..etc) : Variables land_fraction and ice_fraction are available in several IASI-02 data such as IASI-02-TWV land_fraction

Still under investigation

• The pressure values (in Pa) at the layer boundaries (it may be found as static variable)
• Averaging kernels information, descriptors 015043, 015044 and related pressure 010004 : The closest concept we have to an averaging kernel are the of the sensitivity matrix eigenvectors, I am still investigating on that one.

Only for SO2 :

Still under investigation but I decided to add the pressure because it is likely to be available as static variable.

[antoinemerle]

HI @SibylleK,

Following your comments on : TWV.

Antoine needs to investigate on that possibility to use this 008093 : Measurement uncertainty significance instead of using 0 08 023 : First-order statistics and to add a new element 15 as Algorithm uncertainty

First : THanks a lot for the comment and by investigating I found out it was not for TWV but on VII L2 products.
Here is the impacted part of the sequence :

Table references	Element name	note
0 13 165	log 10 of Cloud optical thickness	Cloud optical thickness in Log10
0 20 016	Pressure at top of cloud	Pressure at cloud top
0 20 014	Height of top of cloud	Temperature at cloud top
0 08 023	First order statistics	Specifying we are speaking about : Error / algorithm uncertainty on the following descriptors :
0 13 165	log 10 of Cloud optical thickness	Error on Cloud optical thickness in Log10
0 20 016	Pressure at top of cloud	Error on Pressure at cloud top
0 20 014	Height of top of cloud	Error on Temperature at cloud top
0 08 023	First order statistics	Missing

It is a good remark, and I would be happy to avoid creating a new line in this code table if we can use a different descriptor.
Basically what the scientists explained to me is :
the first iteration is about the geophysical quantity retrieved and then we have its associated algorithm uncertainty also retrieved.

Maybe we can use your descriptors and use the value 2 Random component of uncertainty or maybe another descriptors would be even better ? What do you think ?

Thanks a million for your help @SibylleK

[marijanacrepulja]

Hi @antoinemerle and @SimonElliottEUM

Many thanks for the feedback.

As for GHG

Could you please investigate is it possible to include informations for the a -priori and the average kernels.

1. We would need for the a -priori
   Pressure
   SignificandOfVolumetricMixingRatio

2. We would need the Error in the integratedMassDensity

3. We need pressure at the top and at the bottom of the layer for the
   0 15 021 | Integrated mass density

[amilan17]

https://github.com/wmo-im/CCT/wiki/Teleconference.6.7.June.2023 notes:
Antoine presented the remaining products;

• @antoinemerle will confirm if pressure is in the middle of the column;
• need add a specific code for algorithm uncertainty in 008023 or other table?
• @antoinemerle share sample date in the WMO SharePoint (to be included)

[antoinemerle]

Dear @amilan17 ,

Following the meeting 06/06/2023 : and last comment

• @antoinemerle : Update the VII/WVI sequence (typo in the github proposal)
• @antoinemerle : make a decision on how to deal with "Algorithm uncertainty" ==>After discussing with the science team here in EUMETSAT they definitely request to use the suggestion solution made by SYbille which is using 0 08 093 to measure the ucnertainty. changing the sequence accordingly.
• @antoinemerle : typo in the WMO note column : 0 20 014 | Height of top of cloud | Temperature at cloud top. it should be 0 20 014 | Height of top of cloud | Height at cloud top
• @antoinemerle to push the issue on the Github before end of June
• @antoinemerle to provide the sample data for IASI L2 and VII L2
• @antoinemerle : For GHG and SO2 : need to explain if the specific pressure is the pressure average between the top and bottom of the column/plume (from @marijanacrepulja )
• @amilan17 to give the URL of the SharePoint where Antoine can drop the data

thanks,

[antoinemerle]

[antoinemerle]

Hi @amilan17,

I just pushed all the changes on the dedicated branch : 03b301f

Can you provide me the Slideshare URL in order to allow me to drop the sample files there ?

Thanks a million !

[antoinemerle]

HI @amilan17 ,

Here are all the data generated corresponding to this issue and to the changes applied to this branch.
I already put version 40 for the Master table code in the test data

Note : Due to the Github's restrictions of not being able to upload more than 25MB I had to split the VII L2 in 3 parts... sorry for the inconvenience....

IASI 2 :

• IASI-NG_L2.zip : TWV, CLD, SFC, CO_, GHG, NAC, O3, SO2

VII L2 :

• First_part_VIIL2.zip : VII CLD and CTP
• Second_part VIIL2.zip : OCA
• Third_part_VIIL2.zip : WVI and WVV

[marijanacrepulja]

Hi @antoinemerle,

Many thanks for the samples provided.

I believe the units should be corrected for the descriptors

0 33 118	Relative error percentage	Percentage	2	-10000	15	VII-02-WVV, VII-02-WVI
0 33 119	Forecast error percentage	Percentage	0	-100	8	VII-02-WVV, VII-02-WVI

Instead of Percentage should be %

[antoinemerle]

Hi, @marijanacrepulja ,

Thanks for spotting it!
Updating 033118 and 03119 from percentage to % in de70ce8

[SibylleK]

BUFR-issue161-EPS-SG-Level2_DWDreadbufrxOutput.tar.zip

Using the BUFR tables of the branch (and link version 41 to 40, as the version in the example is 40), the examples could be read with the DWD BUFR reading software.
But only the first 100 Subsets of each BUFR are read, to be able to upload the output here.
The Output of the BUFR seems to be Ok.
(But I don't know whether the values are correct. Please feel free to check:-))

There are no examples with 310090 (IASI SFC?) and 310098 (VII L2 CTP is encoded with 310097 as the CLD) in the provided test-BUFRs.
All other sequences are included in the examples and the BUFR are readable.

From my point of view the validation of the sequences 310087, 310088, 310089, 310091, 310092, 310093, 310094, 310095, 310096, 310097, 310099, 310100 including table B entries and code flag table entries is done.

@antoinemerle can you provide samples for 310090 and 310098?

[amilan17]

https://github.com/wmo-im/CCT/wiki/Teleconference.13.July.2023 notes:

@antoinemerle address comments in PR, provide two more samples for antoine and @SibylleK validate within a week;

[antoinemerle]

Hi @SibylleK ,

Again, apologies for not attending the meeting the other day and for not having replied to you before the meeting ! 😢

• Indeed for 310090 called IASI-NG L2 SFC product, I missed that one during my last delivery
• However, for 310098 it seems it was present in the First_part_VIIL2.zip ?

In any case, to avoid more troubles and confusion : please find below the two product for your review 😃

• New_delivery_for_WMO_Sybille_310090_and_310098.zip

Thanks again for your time to decode and review my product @SibylleK ! 👍

[SibylleK]

Thanks @antoinemerle for the new examples with the two remaining sequences.

Here is the output of the DWD software:
W_XX-EUMETSAT-Darmstadt,SAT,SGA1-IAS-02-SFC_C_EUMT_20230718092907_G_O_20070912101146_20070912101417_O_N____.bin.DWDreadbufrxOutput.zip
W_XX-EUMETSAT-Darmstadt,SAT,SGA1-VII-02-CTP_C_EUMT_20230718110136_G_D_20070912084404_20070912084405_T_B____.bin.DWDreadbufrxOutput100.zip

I only read the first 100 subset of the first BUFR of the provided CTP BUFR examples.
But this should be enough for a successful validation.

Therefore, from my point of view, validation is done.

@antoinemerle  are IASI-NG L2 GHG and IASI-NG L2 SO2 still under investigation for pressure?

[antoinemerle]

HI @amilan17 ,

At the moment, this information is still pending on our side. The scientists were not able to give a clear answer to that question and are still investigating.

The way I propose is to let the comment related to pressure for SO2 and GHG empty at the moment and when we will have this info, I will submit request to add the correct note in the corresponding "comment" column.

What do you think @amilan17 ?

Thanks !

Best,

[antoinemerle]

Hi @SibylleK ,

I only read the first 100 subset of the first BUFR of the provided CTP BUFR examples. But this should be enough for a successful validation.

Therefore, from my point of view, validation is done.
