UNGRIB: Required Fields

WRF requires a number of fields as input.

• 3D Data (e.g. data on pressure levels)
  • Temperature
  • U and V components of Wind
  • Geopotential Height
  • Relative Humidity
    (the code can calculate RH if Specific Humidity is available;
    this is controlled in the Vtable)
     
• 2D Data
  • Surface Pressure
  • Mean Sea Level Pressure
  • Skin Temperature/SST
  • 2-meter Temperature
  • 2-meter Relative or Specific Humidity
  • 10-meter U and V components of wind
  • Soil data (temperature and moisture) and soil height

If any masked field is ingested, then a LANDSEA field is recommended

Water equivalent snow depth (SNOW) is a nice field to have, but not required.

SEAICE is good to have for a high latitude winter case, but it is not required.
