TropOMI L3 OpenDAP
==================

This script is designed to create a custom L3 file from TropOMI NO2 files
streamed remotely from an OpenDAP server. Because it uses OpenDAP, you must
have first configured your `.netrc`, `.urs_cookies`, and `.dodsrc`. 

This example can be edited to work with TropOMI HCHO, VIIRS_AERDB, OMNO2,
OMHCHO, ..., etc.
