Retrieval of Surface Air Specific Humidity Over the Ocean Using AMSR-E Measurements

Retrieval of Surface Air Specific Humidity Over the Ocean Using AMSR-E Measurements

We have developed a new algorithm to estimate the surface air specific humidity over the ocean from AMSR-E data. It should be noted that remarkably reduced random errors of the estimated surface air specific humidity result from using the surface air specific humidity provided by reanalysis data. We...
