The Weather Channel reports on the IMPACTS mission, including its airborne science platforms and instruments. The story features interviews with ER-2 Pilot James G. “Coach” Nelson, IMPACTS Principal Investigator Lynn McMurdie, and Mission Scientists Chip Helms (CRS), Ed Nowottnick (CPL), David Robles (CoSSIR), and Douglas Mach (LIP).
A NASA research field campaign launched in 2020 has flown scientists into winter storms across Wisconsin and the U.S. to answer lingering questions about winter storms. The project ended Feb. 28. We speak with an atmospheric scientist who led the project
A NASA research group called IMPACTS has been flying into winter storms with the hopes of learning more about the weather phenomenon. IMPACTS principal investigator Lynn McMurdie joined FOX Weather on Sunday to explain the group’s mission.
Thank you, everyone, for a wonderful and successful field campaign 2023! As we pack up our equipment and head home, instructions and announcements will follow separately from Dobbins and Wallops.
Lynn, John, Gerry, and I will follow up with the next steps, science team meetings, data workshops, etc. stay tuned!
Have a safe trip back home!
