It is challenging to estimate surface sensible and latent heat fluxes from spaceborne instruments, as these fluxes cannot be directly measured from space. While components of surface heat fluxes can be estimated with various remote sensing instruments, deficiencies in spatial coverage and attenuation from clouds and precipitation can lead to inaccurate measurements of these components, thus leading to inaccurate estimates of surface heat fluxes. Though CYGNSS only contributes surface wind speed measurements, we can combine these improved wind speed observations with other reanalysis and satellite data to improve estimates of surface sensible and latent heat flux. These improved surface heat flux estimates can be used to better understand and observe the role of these fluxes in extratropical cyclogenesis. Additionally, these improved surface heat flux estimates can be applied to the entire CYGNSS mission for other tropical meteorology and climate applications.
