This directory contains data for the Remote Sensing Systems Radiometer Rain Collocations with JPL RapidScat 
L2B Swath Grid dataset. 
*************************************************************************************
Dataset Description (from: http://podaac.jpl.nasa.gov/dataset/RSCAT_COLOCATED_RSS_RADIOMETER_LEVEL_2B_V1):
This dataset contains the multi-sourced microwave radiometer wind speed, rain and cloud liquid water data 
collocated to RapidScat Level 2B wind vector cell (WVC) locations. The corresponding NASA mission is 
officially referred to as ISS-RapidScat. This dataset is produced by Remote Sensing Systems (RSS) with 
direct funding from the JPL RapidScat project. All of the collocated radiometer data is produced by RSS. 
The co-located radiometer sources include: 1) DMSP SSM/I (F15) and SSMIS (F16/F17/F18), 2) Coriolis WindSat, 
3) GCOM-W1 AMSR2 and 4) GPM Core GMI; more details on these radiometer sources and sensors can be extracted 
by scrolling down to the "Platform/Sensor" section below this description. RapidScat is a Ku-band dual beam 
circular rotating scatterometer retaining much of the same hardware and functionality of QuikSCAT, with 
exception of the antenna sub-system and digital interface to the International Space Station (ISS) Columbus 
module, which is where RapidScat is mounted. Unlike QuikSCAT, ISS-RapidScat is not in sun-synchronous orbit, 
and flies at roughly half the altitude with a low inclination angle that restricts data coverage to the 
tropics and mid-latitude regions; the extent of latitudinal coverage stretches from approximately 56 degrees 
North to 56 degrees South. Furthermore, there is no consistent local time of day retrieval. This dataset is 
provided in a netCDF-4 file format that follows the netCDF "classic" model and made available via FTP and 
OPeNDAP.
