Global Hydrology Resource Center (GHRC) Author: Yuling Wu In searching for proper standard names (SD) for our AMSR products, we carefully sift through the CF's SD list, have found proper names for most our products and have proposed a couple of new additions to the CF SD list. One parameter left out of our request #292 is the temperature at 2m. It is a physically quantity of air temperature. However, it has a special importance in meteorology, along with relative humidity at 2m, wind (U and V) at 10m). What separate them from the same physical quantities at other vertical levels are: 1) they are standard measurements at standard surface stations (per WMO); 2) models following the Monin-Obukhov surface layer similarity theory for the surface layer simulation use these quantities and also have them in the output. M-O similarity theory is a very common practice; 3) both NOAA and ECMWF have included these variables in the reanalysis datasets and designated grib types (level type) for them ;4) they are separated from the 3D variables in a model as they are not on the 3D grid.
Surface layer is a very important component of the atmosphere in meteorology, as it is where the energy exchange (heat flux, moisture flux, etc) takes place that drives the dynamics and thermodynamics of the atmospheric systems. And these surface variables provide a measure for the surface layer status and the exchange. So we propose to add following parameters to the Standard Names list: -**Term**: air_temperature_at_2m -**Description**: Air temperature measured at 2 meter height. -**Canonical Units**: K -**Term**: relative_humidity_at_2m -**Description**: Relative humidity measured at 2 meter height. -**Canonical Units**: % -**Term**: wind_speed_at_10m -**Description**: Wind speed measured at 10 meter height. -**Canonical Units**: m s-1 -**Term**: u_component_wind_at_10m -**Description**: U component wind measured at 10 meter height. -**Canonical Units**: m s-1 -**Term**: v_component_wind_at_10m -**Description**: V component wind measured at 10 meter height. -**Canonical Units**: m s-1 -- You are receiving this because you are subscribed to this thread.
