In June of 2016, Dr. Helen Worden became the U.S. Principal Investigator for MOPITT. She is interested in multi-decadal trends of carbon monoxide that indicate changing emissions of pollution with global and regional implications. Her goals for the MOPITT data products are to have a fully characterized long-term archive of atmospheric CO observations with documented precision and bias that can be used to study changes in atmospheric chemistry and emissions of pollution.

She earned her B.A. in Physics from the University of Colorado, Boulder and her PhD in Elementary Particle Physics from Cornell University. She worked several years at JPL/CalTech in Pasadena, CA before moving to Boulder, Colorado to work at NCAR. Awards include the NASA Exceptional Achievement Medal for leading the algorithm development for the EOS/Aura Tropospheric Emission Spectrometer (TES).
