Research Interests

  • High altitude measurements of water vapor and other trace gases, especially those influencing climate and stratospheric ozone
  • Determination and attribution of the inter-annual variability and longer-term trends in stratospheric water vapor and other trace gases
  • Statistical validations of atmospheric composition measurements by satellite-based remote sensors using in situ measurements from balloons and aircraft
  • Improvement of atmospheric composition measurements from mobile platforms including trains, aircraft and balloons

Current Research

I oversee a research team that builds and deploys compact, lightweight, custom-made, balloon-borne frost NOAA point hygrometers (FPHs) that measure atmospheric water vapor profiles from the surface to ~28 km at three sites around the world: Boulder, Colorado; Hilo, Hawaii; and Lauder, New Zealand. Profiles are obtained monthly at each site to compile long-term records of atmospheric water vapor, with a focus on the upper troposphere and lower stratosphere (UTLS) region. The FPH measurements at Boulder date back to 1980 and comprise the longest continuous record of UTLS water vapor in the world. Flight data, including FPH, ozone sonde and radiosonde measurements, are processed, quality controlled and archived by our team here in Boulder.

There are several goals of this research. First (and foremost) is to amass and analyze records of UTLS water vapor over decadal time scales to detect inter-annual variations and longer-term trends in UTLS water vapor driven by variations in atmospheric dynamics. Water vapor changes due to periodic dynamical variations (QBO, ENSO) are present in the FPH records. Our FPH profiles also provide invaluable validation data for UTLS water vapor measurements by satellite-based remote sensors to ensure their accuracy and long-term measurement stability. In 2017 we began launching instrumented balloons in coordination with overpasses of the SAGE-III instrument aboard the International Space Station to validate its measurements of stratospheric water vapor, ozone and aerosols. The FPH time series of water vapor measurements also provide validation data for numerical model simulations of moisture in the UTLS region.

Our team is also regularly involved in field research sponsored by NASA and NSF, predominantly to support scientific campaigns using high-altitude aircraft. We have launched balloons from many locations including New Mexico, California, Hawaii, Guam and Kunming, China.
