European Centre for Medium Range Weather Forecasts (ECMWF) ERA-Interim Data Atmospheric mass, moisture and energy budgets

SOURCE: DSS dataset 627.0

DATA DESCRIPTION: Atmospheric mass, moisture and energy budget products from ERA-Interim; calculations are described here. Note: a T-106 spectral truncation has been applied to these data to lessen grid-scale ringing of the model budgets.

Filenames: Based on field name and time representation: ERAI.VAR.YYY1-YYY2.t-106.nc, where VAR is the capitalized variable name, YYY1=start year, YYY2=end year. One file per field. All time steps in one file.

e.g. ERAI.PS.1979-2016.t-106.nc is the file containing surface pressure for all timesteps.
