Legates / MSU Precipitation ClimatologyEntry ID: JISAO_LEGATES_MSU
Abstract: This WWW page contains analyses and data for a global precipitation climatology that has been produced at JISAO. The spatial resolution of this climatology is 2.5 degrees latitude-longitude. The land data for this climatology is taken from the Legates and Willmott (1990), which is based on historical rain gauge measurements. The ocean precipitation estimates are from the Microwave Sounding Unit ... (MSU) (Spencer 1993) for the years 1979 to 1992.
Spencer and collaborators developed a new MSU precipitation product ("Limb90"), and I got part way through merging it with the Legates and Willmott climatology. This work was never satisfactorily finished, but it is linked here. MSU has difficulty differentiating sea ice from very heavy rainfall, and it is pretty difficult to remove the erroneous gridpoints in a simple manner.
