GPS radio occultation
The National Oceanic and Atmospheric Administration announced plans Feb. 19 to dramatically expand the number of daily radio occultation soundings it acquires from commercial satellites operated by GeoOptics and Spire Global.
The National Oceanic and Atmospheric Administration awarded its first contracts Nov. 20 to purchase radio occultation data from commercial satellite operators to GeoOptics and Spire Global.
The U.S. Air Force and European Centre for Medium-Range Weather Forecasts noted significant improvements in numerical weather prediction models with the recent addition of global navigation satellite system radio occultation datasets.
For the first time, the National Oceanic and Atmospheric Administration is soliciting proposals for commercial radio occultation satellite data to feed operational weather forecast models.
GeoOptics unveiled a data processing system April 14 to improve the accuracy of weather data from its CICERO radio occultation satellite constellation. CICERO stands Community Initiative for Cellular Earth Remote Observation.
The acting administrator of NOAA says the private sector is playing an increasingly important role in its work across the board, including space.
The National Oceanic and Atmospheric Administration seeks to dramatically increase the supply of radio occultation soundings it feeds into weather forecast models.
Spire Global shared the first light data from its new Global Navigation Satellite System (GNSS) Reflectometry satellites at the American Meteorological Society conference in Boston.
Spire Global unveiled Spire Forecast Sept. 11, a product designed to provide the maritime industry with detailed information on atmospheric conditions including global sea surface temperatures, ocean currents, wave heights, surface winds and air temperature.
Tropical storm and space weather forecasts will improve with the help of observations from radio occultation satellites scheduled for launch June 24 on a SpaceX Falcon Heavy, National Oceanic and Atmospheric Administration officials said June 11.
NOAA is soliciting proposals for a second round of a commercial satellite weather data pilot program even as it wraps up the evaluation of the first round.
Spire Global, the San Francisco-based company that operates 48 GPS radio occultation cubesats, says it could provide a persistent view of about 97 percent of Earth with a constellation of 150 satellites.
NOAA and Taiwan’s Ministry of Science and Technology agreed this month to scrap plans for a second set of next-generation GPS radio occultation weather satellites after determining the joint project faced an unwinnable battle to secure funding.
