This file contains monthly average pseudostress values on a 2-degree, 84x30 grid, (1 grid/month) over the Tropical Pacific Ocean. These values were obtained by subjective analysis of a 2-degree by 10-degree grid, which was digitized to a 2-degree grid. The raw data for this analysis included marine surface observations obtained from the National Climatic Data Center (NCDC), Asheville, North Carolina. The current year's analyses are the quick-look product based on reports coming in over the National Meteorological Center (NMC) Global Telecommunication System (GTS). The data are in (meters/sec)**2 with east = positive and north = positive.
