Atmospheric CDRs were created to address the need for Climate Variables, especially Essential Climate Variables (ECVs) as identified by the Global Climate Observing System (GCOS).  The Atmospheric surface ECVs are: Air temperature, Wind speed and direction, Water vapor, Pressure, Precipitation, Surface radiation budget. The Atmospheric upper-air ECVs are: Temperature, Wind speed and direction, Water vapor, Cloud properties, Earth radiation budget (including solar irradiance). The Atmospheric composition ECVs are: Carbon dioxide, Methane, and other long-lived greenhouse gases[3], Ozone and Aerosol, supported by their precursors.  CDRs are often generated by blending satellite observations, in-situ data, and/or model output.
