    Each ER-2 wing also carries instruments: the Cloud Physics Lidar on the right and CosMIR and AMPR on the left, both a type of instrument called a radiometer, which detects microwaves naturally emitted by different types of precipitation, including rain and snow.

    The EXRAD Doppler radar instrument sits in the ER-2’s nose cone. Instrument scientists Matt McMclinden and Charles Turner of installed a hard drive as part of their prep ahead of last week’s science flight.

    While the IMPACTS mission ✈️ is in the field studying snow up close, the Global Precipitation Measurement Mission satellite 🛰 is studying snow — and snowflakes ❄️ — from space! research is looking at snow from the ground up above the atmosphere.

    Both aircraft were also positioned for a GPM satellite overpass comparison, which will provide useful data to evaluate satellite retrievals of cloud properties.

    The third science flight of wrapped up earlier today, with the P-3 and ER-2 sampling the microphysical evolution of precipitation generated by convection and stratiform clouds along an oceanic front. All data are preliminary.

    This helps us better understand the environment associated with winter storms and improve our forecasts in the future.

    With coordination from and atmospheric scientists from and we’re able to profile our atmosphere more frequently and in more areas than usual during

    is an airborne mission but measurements from the ground are important too. During flights, our partners send up extra balloon sondes at some of their nearby stations to measure temp, humidity and wind speed, same as a dropsonde.

    Everyone has a favorite type of snow, so asked some of the scientists what theirs was! ❄️☃️

    We asked researchers and mission support teams what their favorite type of snow was. Some of them couldn't choose!

    Winter storms can cost $300 to $700 million per snow day in lost productivity. Our technologists have worked for decades to improve the technology for determining how much snow will fall from any mass of clouds. ✈️ 🌨️ 🛩️

    Not only did the P-3 collect great data in cloud, the ER-2 was almost directly overhead most of the flight collecting radar measurements of the storm below.

    second science flight took place on Saturday Jan 25, and we got to ride along. The storm system we’d been following all week had plenty of snow to look at up in the clouds. You can read all about it here:

    This week researchers, including those at Goddard, are at to take part in the campaign. IMPACTS is conducting an in-depth study on East Coast snowstorms. Follow for more.

    When we asked the forecasters their favorite type of snow, Phillip went with a different answer. ❄️❄️❄️

    We're back from IMPACTS' 2nd science flight ❄️! It was a great flight for both the P-3 and ER-2 ✈️✈️. We'll have the full report on Monday. Now the crew and team are tucking the P-3 in for the night.

    This process prevents decompression sickness for pilots at high altitudes. 🎥 VC: John Yorks 💻

    3 hours before takeoff, ER-2 pilots are put into full-pressure suits and breathe pure oxygen to help remove nitrogen from the bloodstream. 📸

    Follow as they continue to post about . Yesterday they did a detailed review of the microphysics on the P-3.

    On our Friday tour of the P-3, we saw the instruments on the left or port side of the plane. 1/6

    At morning weather briefing, we had an hour-by-hour forecast of what to expect, in particular when the precipitation starts and the altitudes of the freezing level and Dendridic Growth Zone where snowflakes form! ✈️ ER-2 and P-3 are ready-we are go for flight!

    Have you ever watched a weather forecast and hoped for 𝑏𝑎𝑑 weather? ❄️ The IMPACTS team is eagerly scanning the skies for snowstorms in hopes of flying NASA aircraft into and above them. 📗 Field notes:
