WebNov 14, 2024 · The Cyclone Global Navigation Satellite System (CYGNSS) is a new constellation of eight low Earth orbiting spacecrafts that receive both direct and reflected signals from GPS satellites. Coherent reflection of the GPS signal from standing water over land results in a high surface reflectivity signal in the CYGNSS data. An image … WebApr 12, 2024 · The modulation of the diurnal cycle of precipitation over coastal northern Australia by surface winds was studied using the recently launched NASA Cyclone Global Navigation Satellite System (CYGNSS). Results show a strong connection between the daily cycles of precipitation and surface wind speed, with an offshore wind speed …

WebJul 1, 2024 · GNSS-R background for SM retrieval The GPS satellites transmit GNSS signals, and the CYGNSS satellites receive the forward scattered L-band signals. This forms a bi-static radar configuration at L-band, wherein the received signals contain information about the scattering surface. WebSep 1, 2024 · In this article, we investigated the potential of estimating swell height from delay-Doppler maps (DDMs) data generated by spaceborne GNSS-R. Three observables extracted from the DDM are introduced for swell height estimation, including delay-Doppler map average (DDMA), the leading edge slope (LES) of the integrated delay waveform … simply creative lawn and landscape
