C-130 Aircraft Data [GET]In coordination with the ENNR field campaign , the 53rd Weather Reconnaissance Squadron flew six C-130 flights for a study led by the Scripps Institution of Oceanography to examine atmospheric rivers events associated with heavy precipitation along the US west coast. Three of the flights were flown from Hickam AFB in HI and three from the west coast if the US. A total of 280 dropsindes were available from the 6 missions. Data is available from the PSL web site Data is in FRD format. There is a dry bias corrected version (see UCAR technical note).

HMT-WestThe HMT-West program was well situated to collect meteorological data from land-falling storms along the west coast of the United States. Previous strong El Niños had been associated with greater than average winter time precipitation for the southwest US and there was the potential for flooding and high impact precipitation events. HMT's instrumentation collected high resolution data including quantitative precipitation estimations (QPE), rainfall drop size estimations, temperature, pressure, relative humidities from land-falling storms. More information on HMT including access to data during the ENRR campaign can be found on the Hydrometeorology Testbed (HMT) website. |
TOGA-COARE Historic Wind Profiler dataWind profiler data was collected during the Tropical Ocean-Global Atmosphere (TOGA-COARE) Intensive Operating Period (IOP); November, 1992, through February, 1993. Some data was collected at these sites after the IOP until 2003. Sites include Kiritimati Island, the Galapagos Islands, Darwin, Manus Island in Papua New Guinea, Piura in Peru, Nauru, a country in Oceania, and Tarawa, an atoll and the capital of the Republic of Kiribati, in the central Pacific Ocean. You can access this data through the PSL wind profiler data page. |
Location of ENRR Dropsondes and RaobsTo see what observations were used, there are maps that provide a quick look of locations of dropsondes and ENRR raobs received and successfully decoded into NCEP's production bufr data tanks. Other dropsondes in the area are also plotted. Maps are courtesty of NOAA's NCEI. |
TOGA-TAO: Tropical Moored Buoy ArrayThe Global Tropical Moored Buoy Array Program is a multi-national effort to provide data in real-time for climate research and forecasting. The Pacific component includes the TAO/TRITON array. The program started in 1979. |
North Pacific Analyses during ENRRThe analyses of sea-level pressure (pmsl) over the north Pacific (NPac; 0-60°N, 130°E-110°W) are available during January through April 2016. There are 4 maps per day (at 00, 06, 12, and 18UTC). They are similar to those produced by the NOAA/NWS/Pacific Region Headquarters in real time |
Satellite ArchivesNOAA keeps an archive of satellite products via their GIBBS Global ISCCP B1 Browse System which includes 1974-present. |
