SHOW ER-2 Campaign

ISM CREATE student Daniel Letros has a good excuse for missing PH549 this summer.  He will be heading to the Armstrong Flight Research Center at Edwards Airforce Base in California.  He is part of a team of CSA, NASA and UofS ISAS scientists, including ISM collaborators Dr. Doug Degenstein and Dr. Adam Bourasa.

The program will use a Spatial Heterodyne Spectroscopy optical technique to measure water vapour features the upper troposphere-lower stratosphere region with limb viewing geometry.  The SHOW (Spatial Heterodyne Observation of Water) ER-2 campaign will be carried out on NASA’s ER-2 science aircraft in mid-July.  The ER-2 is able to fly into the lower stratosphere at subsonic speeds, enabling direct stratospheric sampling and observation.

Two flight paths at an altitude of 22km will be flown, one going north over the western United States and the other southeast over the Pacific. The goal of the campaign is to measure the density of water vapour in the upper atmosphere and improve predictive models.

Good luck with the launch Daniel.
