NOAA Issues RFP for Commercial Weather Data Pilot Program
NOAA has issued a request for proposals for the second phase of its commercial weather data pilot program.
The program’s goal is to determine whether GPS radio occultation data from commercial satellites can be used to improve weather forecasting. Radio occultation involves the change in a radio signal as it passes through Earth’s atmosphere, allowing for the measurement of physical properties there.
The firm-fixed price contracts for the second phase will run from Aug. 27, 2018 through Sept. 30, 2019. The data collection and delivery period will run from Oct. 1, 2018 to June 30, 2019.
Companies are required to provide at least two periods of at least three consecutive months of radio occultation data during the collection period. A minimum of 500 atmospheric soundings per day are required. Data must be delivered to NOAA at least once per week.
NASA issued contracts to GeoOptics and Spire for the first phase of the pilot program in September 2016. Space News reports the program did not go very smoothly, but that NOAA officials had learned a number of key lessons from it that are being included in the second phase.
GeoOptics’ contract was terminated when the company was unable to provide data because of delays in the launch of its first satellites.
While Spire did provide data, NOAA officials said later that the quality of the data fell short of expectations. “We have gone through one contract already with the radio occultation community, and we found that the data aren’t accurate enough or comprehensive enough yet to meet our observing requirements,” Stephen Volz, NOAA assistant administrator for satellite and information services, said in January. Spire said that the data from its constellation of cubesats has improved significantly since the end of that initial round of the pilot program in April 2017.
NOAA officials have said for several months that they are working on a report analyzing the results of that first round of the Commercial Weather Data Pilot. However, NOAA spokesman John Leslie said May 7 that the report is still “nearing competition” within the agency and will be released publicly once it is completed.
Proposals for phase two are due on May 25.
