PMD Imager


The PMD imager is a widget-based IDL tool written to display SCIAMACHY Nadir states on a world map projection, using the high spatial resolution of the pmd signals.



The imager can be used for quick inspection of SCIAMACHY Nadir states, visual cloud detection and geolocation checks. And of course for making highest resolution (pmd's have a spatial resolution of 7.5 km x 30 km) true colour images of the earth! In order to successfully use the tool you will need IDL, the BEAT software and a SCIAMACHY L1C file with extracted pmd values.

Here are some screenshots of the imager and it's capabilities:

It can be used as a quick visual cloud detector:

Geolocations can be checked with options for displaying both backward and forward scans or only (stretched) forward scans, either filled

or non-filled:


Using different PMD channels, attention can be focused on cloud detection (e.g. using pmd 1, UV) :

or land-sea contrast (pmd 4, IR):
