Question

How do I read and calibrate (i.e., convert to brightness temperatures) AVHRR data from CLASS?

Answer

AVHRR data obtained through CLASS is available in a number of formats (which are summarized below). However, there are few tools to work with these formats directly.

NCDC has developed a Java-based tool to convert POES data to netCDF format. This allows researchers a variety of tools in various programming languages to work with the AVHRR data. The AVHRR converter is described here.
