Microwave Radiometer Retrieval Data Available for AMF Sites

An example plot from the MWRRET VAP for 11/9/2007 at Black Forest, Germany: (top) Brightness temperatures measured by the microwave radiometer (MWR). Orange and blue lines indicate potential measurement spikes due to precipitation; (middle) retrieved precipitable water vapor from the new physical method (blue) and the original statistical method (green); (bottom) retrieved liquid water path from the new physical method (blue) and the original statistical method (green). Sonde launch times are indicated in purple in the middle panel.

The Microwave Radiometer Retrievals (MWRRET) value-added product (VAP) has now been processed for the following ARM Mobile Facility (AMF) deployments:

Preliminary data are also available for the MAGIC deployment of the AMF in the evaluation area of the ARM Data Archive. The MAGIC data do not currently include the final bias correction. These data will be reprocessed to apply this correction when final meteorological and active remote sensing of cloud locations (ARSCL) input data are available.

The MWRRET VAP retrieves column precipitable water vapor (PWV) and liquid water path (LWP) from the 2-channel microwave radiometers using a physical retrieval methodology that provides improved retrievals over the standard statistical coefficient method.
