This artifact processes data coming from [ERA5 monthly averaged reanalysis](https://cds.climate.copernicus.eu/datasets/reanalysis-era5-single-levels-monthly-means?tab=download) and contains
monthly averaged surface fluxes and runoff rates.

## Spatial Coverage
### Spatial Coverage

- 1 degree latitude x 1 degree longitude grid
- -90N to 90N and 0E to 359E
- The latitudes are reversed during processing to be in increasing order

The shared variables, which are all stored as Float32s and defined on the latitude, longitude, and time dimensions, are:

This is the mean surface latent heat flux in units of W m**-2. No processing is done to this variable other than flipping the latitude dimension.

### `msshf`

This is the mean surface sensible heat flux in units of W m**-2. No processing is done to this variable other than flipping the latitude dimension.

## `mssror`

This is the mean sub-surface runoff rate in units of kg m**-2 s**-1. No processing is done to this variable other than flipping the latitude dimension.

This is the mean surface runoff rate in units of kg m**-2 s**-1. No processing is done to this variable other than flipping the latitude dimension.

## `msuwlwrf`
### `msuwlwrf`

This is the mean surface upward long-wave radiation flux in units of W m**-2.
This variable is created during processing by taking the difference of
mean surface downward long-wave radiation flux and mean surface net long-wave radiation flux, and then flipping the latitude dimension.
