The Rapid Refresh is run at the NOAA National Centers for Environmental Prediction (NCEP). It is based on the framework of the Weather Research and Forecasting model (WRF); the Global Forecast System (GFS) provides the boundary parameters. The grid points are spaced every 13 kilometres (8.1 mi), with 50 vertical intervals extending up to the 10 ...
The sensor on weather satellites that picks up the data transmitted in HRPT is referred to as an Advanced Very High Resolution Radiometer (AVHRR) for NOAA satelites. [1] Broadcast signal The working frequency band for HRPT is L Band at 1.670–1.710 GHz and the modulation type isBPSK. [2]
Map of regions covered by the 122 Weather Forecast Offices. The National Weather Service operates 122 weather forecast offices. [1] [2] Each weather forecast office (WFO or NWSFO) has a geographic area of responsibility, also known as a county warning area, for issuing local public, marine, aviation, fire, and hydrology forecasts.
NOAA's GOES-R Series of satellites is designed to improve the forecasts of weather, ocean, and environment by providing faster and more detailed data, real-time images of lightning, and advanced monitoring of solar activities and space weather. GOES-17 can collect three times more data at four times image resolution, and scan the planet five ...
The NAM is run four times a day (00, 06, 12, 18 UTC) out to 84 hours, with 12 km horizontal resolution and with three-hour temporal resolution, providing finer detail than other operational forecast models. Its ensemble is known as the Short Range Ensemble Forecast (SREF) and runs out 87 hours.
An example of a forecast product from the GFS, in this case a 96-hour forecast of 850 mb geopotential height and temperature. The Global Forecast System (GFS) is a global numerical weather prediction system containing a global computer model and variational analysis run by the United States' National Weather Service (NWS).
The Weather Prediction Center (WPC), located in College Park, Maryland, is one of nine service centers under the umbrella of the National Centers for Environmental Prediction (NCEP), a part of the National Weather Service (NWS), which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Government.
The charts are stored in BSB format. "[The BSB file format] is a proprietary format of BSB Electronic Charts, LLP (bought by MapTech, Inc.)." [1] Image manipulation tools such as GDAL can read the image information, but there also is georeferenced data in the navigational charts.
