Assessment of the NCEP-DOE reanalysis-2 and TOVS Pathfinder a moisture fields and their use in Antarctic net precipitation estimates

Zou et al validate moisture fields from the NCEP-DOE reanalysis-2 (R-2) and Television Infrared Observational Satellite Operational Vertical Sounder (TOVS) Pathfinder A using the Special Sensor Microwave Imager (SSM/I) retrievals over the Southern Ocean. It is shown that the spatial distributions of...

Description
Summary:Zou et al validate moisture fields from the NCEP-DOE reanalysis-2 (R-2) and Television Infrared Observational Satellite Operational Vertical Sounder (TOVS) Pathfinder A using the Special Sensor Microwave Imager (SSM/I) retrievals over the Southern Ocean. It is shown that the spatial distributions of the annual mean statistics of the total precipitable water are similar among SSM/I, R-2 and TOVS Pathfinder A for both the eddy and mean components. However, transient statistics show that the R-2 total precipitable water agrees with SSM/I with a correlation of 0.77 over the Southern Ocean while the TOVS Pathfinder A moisture is almost uncorrelated with the SSM/I data.
