CYGNSS Version 2.1 Level 3 Daily Wind Speed Over the Tropical Oceans

Tuesday, October 30, 2018

The Cyclone Global Navigation Satellite System (CYGNSS) is a NASA Earth System Science Pathfinder Mission that is intended to collect the first frequent space‐based measurements of surface wind speeds in the inner core of tropical cyclones. Made up of a constellation of eight micro-satellites, the observatories provide nearly gap-free Earth coverage using an orbital inclination of approximately 35° from the equator, with a mean (i.e., average) revisit time of seven hours and a median revisit time of three hours. This inclination allows CYGNSS to measure ocean surface winds between approximately 38° N and 38° S latitude. This range includes the critical latitude band for tropical cyclone formation and movement. More information on the CYGNSS Mission can be found here: https://podaac.jpl.nasa.gov/CYGNSS

CYGNSS daily wind speeds in this animation are provided by the CYGNSS Level 3 Science Data Record Version 2.1 (https://doi.org/10.5067/CYGNS-L3X21) covering 18 March 2017 through 21 October 2018.
