da Silva et al. 1994: Surface Marine Data

UWM/COADS Analyzed Fields - Overview

Period: 1945-89, monthly climatology and anomalies

Grid: 1x1 degree, global

Objective Analysis: Sucessive correction method with Barnes' weight function. Same response function as Levitus' Climatological Atlas of the World Oceans. Unanalyzed monthly means, standard deviation and number of observations also available.

Main Features: All calculations from individual observations Wind speed correction (revised Beaufort equivalent scale) Stability dependent transfer coefficients (Large&Pond) Heat and fresh water fluxes fine tuned with oceanic constraints (simple linear inverse calculation). Sensitivity fields provided to allow for other oceanic constraints.

This data set was produced at University of Wisconsin-Milwaukee (UWM) by Arlindo M. da Silva and Christine C. Young in collaboration with Syd Levitus from NOAA/National Oceanographic Data Center. Since then both AMdS and CCY have left UWM, and inquires about the data set should be directed to the address below.
