Evolution of the NASA Multi-Scale Ultra-High Resolution (MUR) sea surface temperature (SST) response to the 2018 Atlantic hurricane season. It is common to observe trails of cooler water, or cold wakes, along hurricane tracks as a result of wind-induced mixing and turbulence that brings cold waters at depth to the surface. The cold wakes associated with the 2018 Atlantic tropical cyclones are clearly observed as waters approximately 2°C cooler from normal that persisted for several days. (MUR SST DOI: 10.5067/GHGMR-4FJ04).

Evolution of the NASA Soil Moisture Active Passive (SMAP) sea surface salinity (SSS) response to the 2018 Atlantic hurricane season. It is common to observe patches of 1) salinity freshening due to enhanced precipitation and 2) salinity increase due to wind stress-generated vertical mixing, wherein increased salinity from a mid-level maximum is brought to the surface. The two effects are clearly observed along the tracks of the 2018 Atlantic tropical cyclones. (SMAP SSS DOI: 10.5067/SMP42-3TPCS).

Evolution of the NASA Multi-Scale Ultra-High Resolution (MUR) sea surface temperature (SST) response to Hurricanes Florence, Helene and Isaac of 2018. It is common to observe trails of cooler water, or cold wakes, along hurricane tracks as a result of wind-induced mixing and turbulence that brings cold waters at depth to the surface. The cold wakes associated with Florence, Helene, and Isaac are clearly observed as waters approximately 2°C cooler from normal along the hurricane track that persisted for several days. (MUR SST DOI: 10.5067/GHGMR-4FJ04).

Evolution of the SMAP sea surface salinity (SSS) and soil moisture responses to Hurricanes Harvey, Irma, and Maria of 2017. The ocean salinity response to hurricanes is a combination of two competing effects: 1) salinity freshening due to enhanced precipitation and 2) salinity increase due to wind stress-generated vertical mixing, wherein increased salinity from a mid-level maximum (found in typical salinity profiles) is brought to the surface. The two effects are clearly observed along the tracks of Harvey, Irma, and Maria.

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.
