This web sitedisplays data locations that have been through various quality control processes and are available for model input and client use. The top caption displays the latest time window, data cut and when the plots were generated.  The next line presents a selction of twelve data cuts, three each for time windows, 00Z, 06Z, 12Z and 18Z.  The Early data cut encompasses data 3 hours before and 1 hour after the specified time (00z,06z,12z,or 18z).  Main corresponds to a 6 hour window, 3 hours before and after.  Late still corresponds to a 6 hour window, but is processed 8 hours later to catch "late" transmissions. The following data types are listed in the left column. RAOB Rawinsonde data PIBAL Pilot balloon sounding data SHIP Ship and coastal marine data SHIPCHECK Ship location check BUOY Ocean buoy data BUOYCHECK Drifting buoy check LAND Surface land data PAOB Australian bogus pressure data AMDAR Aircraft Meteological Data Relay (AMDAR) data AIREPS AIREPS (air reports) have multiple sources, but are primarily from Air Traffic Control (ATC) and are primarily for over ocean reporting. These are semi-automatic reports from aircraft to ground and are encoded by ATC personnel. MDCRS Meteorological Data Collection and Reporting System (MDCRS) data CIMSS Cooperative Institute for Meteorological Satellite Studies(CIMSS) at the University of Wisconsin. Feature-tracked wind data from the GOES and METEOSAT satellites. AFWA METE Air Force Weather Agency geosynchronous METEOSAT satellite processed data AFWA GOES Air Force Weather Agency geosynchronous GOES satellite processed data NESDIS National Environmental Satellite Data and Information Service(NESDIS) feature-tracked wind data. EUMET/JMA Feature-tracked wind data from the EUMETSAT and JMA satellites SSMI Special Sensor Microwave Imager data from the Defense Meteorological Satellite Program satellites F11, F13, F14, and F15 QUIKSCAT SeaWinds Scatterometer aboard the QuikSCAT satellite SCAT (ERS2) Earth Remote Sensing (ERS) scatterometer satellite (ERS2) data from the Eurpean Space Agency (ESA) WINDSAT WINDSAT is a joint IPO/DoD/NASA risk reduction demonstration project intended to measure surface ocean surface wind speed and wind direction from space using a polarimetric radiometer on board the Coriolis satellite. ATOVS Advanced Tiros Operational Vertical Sounder (ATOVS) data from NOAA polar orbiting satellites MODIS Moderate Resolution Imaging Spectroradiometer (MODIS) data from the Terra (EOS AM) and Aqua (EOS PM) satellites AVHRR Advanced Very High Resolution Radiometer (AVHRR) data from NOAA polar orbiting satellites AMSU-A Advanced Microwave Sounding Unit - A (AMSU-A) data from NOAA polar orbiting satellites AMSU-B Advanced Microwave Sounding Unit - B (AMSU-B) data from NOAA polar orbiting satellites HIRS High Resolution Infrared Sounder (HIRS/3)and High Resolution Infrared Sounder (HIRS/4) data from NOAA polar orbiting satellites MHS Microwave Humidity Sounder (MHS) data from NOAA EUMETSAT METOP polar orbiting satellites IASI Infrared Atmospheric Sounding Interferometer (IASI) data from EUMETSAT METOP polar orbiting satellites AMSU/AIRS Advanced Microwave Sounding Unit (AMSU) and Atmospheric Infrared Sounder (AIRS) data from the AQUA polar orbiting satellite Two numbers are shown in the coverage plots, observation count and station or reported data locations.  The count is always greater than or equal to the number of locations due to multiple observations at a single location within a 6 hour window.  Records are kept for the past 30 days. If a rawinsonde or pilot balloon station has reported observations 75% of the time during the past 30 days, then a red circle surrounds the colored data dot location. Being empty indicates no observation was made at that otherwise reliably reporting station. The 30 DAY graphs show observation count values for the past 30 days for that particular data cut, time window and data type.
