Instrument : MWR
Microwave Radiometer
Instrument Categories
Radiometric, Cloud Properties, Atmospheric Profiling
General Overview
The Microwave Radiometer (MWR) provides time-series measurements of column-integrated amounts of water vapor and liquid water. The instrument itself is essentially a sensitive microwave receiver. That is, it is tuned to measure the microwave emissions of the vapor and liquid water molecules in the atmosphere at specific frequencies.
Output Value-Added Products
This instrument is an input to the following value-added products, which provide improved measurements or derived quantities.
- 1mwravg : Microwave Radiometer (MWR): brightness temps and water amounts, 1-minute avg
- 5mwravg : Microwave Radiometer (MWR): 5-minute average integrated vapor and liquid water
Output Datastreams
- mwrlos : Microwave Water Radiometer (MWR): water liq. & vapor along line of sight (LOS) path
