Map Plots of PWV Results
We display the current
color contour PWV map based on our processing results.
PWV is plotted in units of cm. You can also take
a look at a near-real-time comparison
GOES PWV image for the same area at The
CIMSS Realtime GOES Page . The stations for which the wet delay
was estimated in the last solution, shown as white squares on the map,
are used to generate the contours (GMT routines are used to generate the
maps.) Please note that for regions with sparse or no wet delay sites, the contour
maps can contain incorrect values. When surface pressure and temperature are not
available we use default pressure and temperature for the dry delay computation. These
stations, shown by red squares are not used in generating the PWV map.
We have also generated total
electron density maps for the region. These TEC
maps are generated from 1 hour of dual frequency observations of the network
and the TEC units represent the total number of electrons in a
vertical column of 1 square meter. Click here for
postscript total electron density maps.
