![]() ![]() ![]() And the ability to image inland waterbodies with high resolution has been leveraged to demonstrate two new measurement capabilities.”Ī new measurement capability by CYGNSS is featured in a recent article in Remote Sensing titled “Response to Variations in River Flowrate by a Spaceborne GNSS-R River Width Estimator”. Ocean wind measurements in tropical cyclones have been successfully introduced into numerical hurricane forecast models. An important refinement to the engineering calibration has been developed. “This past year has seen progress on several fronts. In year 2, the ocean wind retrievals were refined and characterized and investigations of observations over land began in earnest. Year 1 was spent on engineering commissioning and initial ocean wind measurements. Much has happened in that time and the future looks very promising, with all eight microsatellites healthy and operating continuously in their nominal science data-taking mode. “CYGNSS was launched on Decemat 13:27:21 UTC and today marks the completion of its third year on orbit. Chris Ruf looks at what the mission has accomplished, and where it’s going in a new blog post at NASA’s Earth Observatory blog. The eight-satellite constellation is celebrating three years on orbit!ĬYGNSS Principal Investigator Prof. Credits: NASAįor more information about this exciting new application, go here. ![]() The data that CYGNSS provides will enable scientists to probe key air-sea interaction processes that take place near the core of storms, which are rapidly changing and play a crucial role in the beginning and intensification of hurricanes. The CYGNSS satellites will make frequent and accurate measurements of ocean surface winds throughout the life cycle of tropical storms and hurricanes. If both are present at the same time and place, the probability of locusts being there increases and this provides advance warning for mitigation efforts to be deployed before they can fly.įlying over the Atlantic Ocean offshore from Daytona Beach, Florida, a Pegasus XL rocket with eight Cyclone Global Navigation Satellite System, or CYGNSS, spacecraft is released from the Orbital ATK L-1011 Stargazer aircraft and the first stage ignites at 8:37 a.m. Moist sub-surface soil conditions are identified by CYGNSS which support their eggs, and healthy vegetation is identified by MODIS NDVI which is necessary to sustain young locust development. Science team members at the NASA Marshall Space Flight Center, University of Alabama Huntsville, and UCAR are working with the US Agency for International Development and the United Nation Food and Agriculture Organization to develop a method for detecting the locations of the young locusts. We look forward to many more year of successful operation and scientific exploration.ĬYGNSS measurements are being used to help detect the breeding grounds for a major locust outbreak occurring in East Africa. Over land, measurements of flood inundation and soil moisture are also continuously made, to be used in hydrological process studies and for disaster monitoring. They continue to make 24/7 measurements of ocean surface winds, both globally and in tropical cyclones, which can be used to study meteorological processes and improve numerical weather forecasts. The constellation of eight spacecraft are all healthy and operating nominally in their orbits 524 km above the Earth. Another Senior Review will occur at that time for another three-year extension. NASA recently completed its Senior Review process for the CYGNSS mission and we have been approved to continue science operations through 2023.
