* Locations are in the UTM (Zone 33N) map projection with datum EUR-M
All sampler locations are used as receptors, and these are the actual sampler locations
reporting values during the particular experiment.
Meteorological Processing
Data from surface stations (i.e., 10m to 30m masts), towers, SODARs, minisondes
and radiosondes are used to drive three-dimensional CALMET wind and temperature
fields for the modeling domain. These data are extracted from the GF-3 databank
files, averaged to one-hour periods where necessary, and reformatted as one
SURF.DAT, one SEA.DAT, and six UP.DAT files for input to CALMET. Wind
directions in the databank files are modified by adding two degrees to the geodetic
(virtually the same as magnetic) directions to reference them to grid-North in the
UTM Zone 33N projection. Specialized codes are developed for accomplishing these
tasks. Locations of those stations used in this modeling are shown in Figure 4-6.
