Abstract

The CAST dataset contains data produced by the NERC Co-ordinated Airborne Studies in the Tropics (CAST) project. CAST was a collaborative initiative with NASA's Airborne Tropical Tropopause Experiment (ATTREX) programme to study the Tropical Tropopause Layer (TTL) over the Pacific Ocean and South East Asia.

This dataset contains measurements of ozone, carbon dioxide, methane and other atmospheric chemical species.
