Model
The
Numerical Weather Model of NOAA/NCEP
The National
Centre for Environmental Prediction (NCEP) of the National Oceanic and
Atmospheric Administration (NOAA) operates the Global Data Assimilation System
(GDAS). The final analyses of this weather model are used for this project.
The three-dimensional output fields of this model have a resolution of
1°x1° and 26 vertical layers. These layers contain geopotential
heights for the corresponding pressure level (between 1000 hPa and 10 hPa)
as well as the temperature.The relative humidity is given for 21 vertical
layers (they end at 100 hPa). In horizontal direction the data are stored
in matrix layout with 181 rows and 260 columns corresponding to a resolution
of 1°x1°.
From these
