ECMWF Deterministic Model Analysis Data on pressure levels in GRIB1 (D1D)



This data set contains the European Center for Medium range Weather Forecasting (ECMWF) deterministic forecast model analysis data on pressure levels (and a soil layer) in GRIB1 format. The forecast files and analysis files on hybrid levels are in the companion data sets (see below). For each day there are global 0.25 degree resolution analysis files at 00, 06, 12, and 18 UTC. This data set is password protected. Contact Steve Williams (see below) for password information. This is a large data set with each day containing ~1.7 Gb in 4 files. Each order can contain a maximum of 16 Gb of data (~9.5 days). For very large orders, it may be preferable for you to access these data via a loaner external hard drive. Please contact Steve Williams (see below) for these very large orders.
