MERRA2 reanalysis data are used as forcing. Additionally transient and monthly aerosol data of the MACv2 climatology are prescribed. The model uses a rotated grid with 566 x 481 grid points and a grid point distance of 0.0625 degrees, the rotated North pole is located at 162.0 W, 39.25 N. The published data excludes the sponge zone and have 526 x 441 grid points. In rotated coordinates the published simulation data extends from 22.64 W to 10.18 E, 11.2 S to 16.3 N, in geographical coordinates this corresponds to about 12 W to 30 E, 39 N to 60 N. institution: Helmholtz-Zentrum Geesthacht, Institute of Coastal Research, Germany source: int2lm_131101_2.00_clm4, COSMO-CLM5.0_clm14_aerosol_gust (available at DKRZ's LTA WDCC service), http://www.cosmo-model.org/content/model/documentation/core/default.htm contact: http://coastmod.hzg.de originator: Ronny Petrik crs: EPSG:4326 Dr. Ronny Petrik Maritime Geoinformation Division not filled pointOfContact NetCDF COSMO-CLM MERRA2 hindcast openSource regional modelling renewable energy ODC-By-1.0: Open Data Commons Attribution License (ODC-By) v1.0 https://opendatacommons.org/licenses/by/1.0/ eng; USA -17.0 35.0 39.0 66.0 calendrical 2002-01-01 2018-12-31 geometric height geometric height; unit: not filled lagrangian_tendency_of_air_pressure "tendency_of_X" means derivative of X with respect to time. The Lagrangian tendency of a quantity is its rate of change following the motion of the fluid, also called the "material derivative" or "convective derivative".

If the vertical air velocity is upwards, it is negative when expressed as a tendency of air pressure; downwards is positive.[CF-Standard Name]; unit: not filled air_temperature Air temperature is the bulk temperature of the air, not the surface (skin) temperature.
