HadISDH.marine Build Process

HadISDH.marine is a monthly 5° by 5° gridded global ocean surface humidity climate monitoring dataset created from in-situ sub-daily synoptic ship data. The data have been quality controlled and bias adjusted for changing ship heights and instrument types. Monthly mean climate anomalies are provided alongside uncertainty estimates, actual values, climatological means and standard deviations for specific humidity, relative humidity, vapour pressure, dew point temperature, wet bulb temperature, dew point depression in addition to the simultaneously observed temperature. This diagram shows an overview of the build process.
