OU/NSSL CLAMPS Microwave Radiometer and Surface Meteorological Data from LAPSE-RATE

<p>The microwave radiometer measures downwelling microwave radiance in 14 channels from 22.2 to 60.0 GHz at 1 s temporal resolution. It is one of the core instruments in the Collaborative Lower Atmospheric Mobile Profiling System (CLAMPS-1) facility.</p> <p>A simple statistical retrieval is performed to retrieve precipitable water vapor (PWV) and liquid water path (LWP) from the observations at 23.8 and 31.4 GHz (Turner et al. 2007).</p> <p>This microwave radiometer has a Vaisala all-weather met station included. This station is positioned about two feet above the back of the CLAMPS trailer. It is possible that the trailer is affecting these met station observations in some conditions. Note that the wind data in these files are likely not representative of true environmental wind. Due to power requirements, CLAMPS was positioned close to a building, which likely influenced the wind speed and direction. Any wind data should be used with caution.</p> <p>&nbsp;</p> <p>References:</p> <p>Turner, D. D., S. A. Clough, J. C. Liljegren, E. E. Clothiaux, K. E. Cady-Pereira, and K. L.
