Forecast_Data_tb_v_forecast: Array of 32 bit Reals [y = 0..1623][x = 0..3855]
long_name: Composite resolution Catchment model forecast 1.41 GHz V-pol brightness temperature. Model forecast brightness temperatures that correspond to 36 km observations from the L1C_TB product are aggregated from 9 km to 36 km and then posted at 9 km for convenience. Output is only stored at times and locations for which input SMAP Level 1 or Level 2 data are ingested. If more than one overpass occurs for a given grid cell within the assimilation time window, output represents average over all overpass times.

Observations_Data_tb_v_resolution_flag: Array of 32 bit Unsigned integers [y = 0..1623][x = 0..3855]
long_name: Flag indicating the effective resolution of V-pol brightness temperature composite fields (tb_v_obs, tb_v_forecast, etc.): 1=36 km, 2=9 km. Type is Unsigned32. Output is only stored at times and locations for which input SMAP Level 1 or Level 2 data are ingested. If more than one overpass occurs for a given grid cell within the assimilation time window, output represents average over all overpass times.

Observations_Data_tb_v_obs_assim: Array of 32 bit Reals [y = 0..1623][x = 0..3855]
long_name: Assimilated value after model-based quality control and climatological adjustment (scaling) of tb_v_obs for consistency with the land models seasonally varying mean brightness temperature climatology. Observed brightness temperatures that originate from 36 km L1C_TB files are posted at 9 km here for convenience (as average over the fore and aft brightness temperatures, which are stored separately in the L1C_TB product). Output is only stored at times and locations for which input SMAP Level 1 or Level 2 data are ingested. If more than one overpass occurs for a given grid cell within the assimilation time window, output represents average over all overpass times.

long_name: Time values as counts of International System (SI) seconds based on the J2000 epoch in Ephemeris Time (ET). The J2000 epoch starting point is January 1, 2000 at 12:00 ET, which translates to January 1, 2000 at 11:58:55.816 Universal Coordinated Time (UTC). Type is Float64.
