Env only plot evaluation

Description of what to look for in the --suite Environment plot after the 100year Env-Only "pre-run":

In general:

An ideal outcome has all traces flat-lined by the end of the pre-run.

• Non-calculated values should be constant. Tair for example. This is the average annual temperature over the first X years, and in this "pre-run" we are using the same climate year to year, so the average annual value should be the same for the entire 100 year "pre-run"

• Calculated values may not be constant, but should stabilize by the end of the 100 years.

Specifically:

1st panel:

• values in degrees C, approx reasonable range: -40 to 25?
• Tair: Not Calculated. Should be constant.
• TDeep & TShallow: Calculated. Should not be identical, but it is not immediately clear what the relationship should be when viewed as an average like this. In the summer TShallow should be warmer than TDeep and in the winter, colder.
• TMineA,B,C: Calculated. Should probably be similar. Being Mineral Layers, they should be deeper and should therefore be warmer and more stable than some of the shallower readings.

2nd panel:

• values measured in mm, approx reasonable range 0-300mm?
• EET: Calculated. "Actual?" evapo. transpiration
• PET: Calculated. Potential evapo. transpiration, not taking into account drought
• PET should always be greater than or equal to EET.
• VPD: Calculated. Vapor pressure deficit. Values should be positive, 0 or greater. Computed from vapor pressure and transpiration, measure of water regulation by vegetation without drought stress as opposed to the amount of water actually in the soil?
• Rainfall, Snowfall. Sort of Calculated, but I think should still come out constant on the plot? Not sure what the values are reported as here, mm or m. Also not sure if the snow has been converted from snow depth to snow water equivalent. Ideally snow+rainfall should equal precip. May want to add precip to this plot?
• Approx. reasonable precipitation @Toolik ~300mm (Checked this by Summing first year of one of the projected climate files)

3rd panel:

• values measured in m, depth from surface (z)? or thickness (dz)?
• Water Table & Active Layer Depth: Calculated. In a permafrost area, the Water Table should be shallower than the Active Layer (liquid water can't get down thru the permanently frozen ground).
• In DOSTEM, Active Layer Depth is buggy and re-initialized to zero when the ALD gets to the lowest soil layer.

4th panel:

• VWC, Volumentric Water Content. measured as a percentage. 0 is dry, 1 is completely saturated.
• In general deeper layers should be more saturated, shallow layers dryer, so the behavior after the 50yr step is actually preferred.
• Ignore step @~50years for now (7/17/2015).

5th panel:

• PAR, Photosynthetic Active Radiation. Not sure the measurement.
• PAR Absorb should be lower than PAR
• Mostly ignore for now (7/17/2015)

More notes

Although -10C seems low for average annual temperature, I checked against our inputs. This is against a recently created climate file from cccma_cgcm3_1_sresa1b_2001_2100. This command looks at the first year of data. I averaged it by hand to ~ -10C
