This is the CFSR dataset that can be used to calculate air density for wind energy purposes using the equations presented in The NetCDF file contains mean fields of monthly means from 2001 to 2010 of the variable temperature, surface pressure and specific humidity. The horizontal grid resolution is 0.5 degrees and covers the whole globe. These fields were used in the WAsP software version up to version 12.5 to calculate the air density at specified heights above mean sea level. The WAsP software ( is the industry standard method to calculate the annual energy production of wind farms.
