What is PAOBS?
[9/10/96] PAOBS (Australian Surface Pressure Bogus data for the Southern Hemisphere) is a product of human analysts who estimate sea-level pressure based on satellite data, conventional data and time continuity. The PAOBS were mislocated in the 1996 version of reanalysis products. • What is the period of record for PAOBS problem existed?[9/10/96] Data in the primary archive had mislocated PAOBS for input during the period 01Jan1980 through 02Apr1993. PAOBS are used only in the Southern Hemisphere and many of these PAOBS were rejected by the data assimilation. Long range Reanalysis plans call for rerunning the analysis every few years, and PAOBS positions will be handled correctly in future runs. • How does Reanalysis handle the surface water budget?[8/30/96] Reanalysis keeps track of soil wetness at various levels in the soil as well as on the canopy, and the fields themselves are available as a part of the reanalysis dataset. The budget equation is based on precipitation, evaporation,
