The MLS CH3OH Product

Contact: Michelle Santee

Basic Information

Methanol (CH3OH) is one of the most abundant organic gases in the atmosphere (exceeded only by methane). It plays a key role in the oxidative capacity of the atmosphere. The primary sources of atmospheric methanol are the growth and decay of plants and biomass burning.

How it is part of MLS Science Objectives

As a biomass burning product, CH3OH, especially when used in conjunction with other pollution markers measured by MLS, will help determine the extent to which fire emissions affect the composition of the upper troposphere / lower stratosphere.

How EOS MLS measures CH3OH

The standard methanol product is taken from the 640 GHz retrieval.
