We took advantage of the only sunny day we'll have in (at least) the next ten days, so we spent it on the beach and decided a polar plunge was a good idea! 🥶🧊 #ARCSPIN CSU Atmos Sci

Check out Dr. @Marina_nieto91's talk at #AAAR2021 conference on Airborne Murine Coronavirus Persistence in Saliva Microaerosols (1SI.7), where she will discuss viral infectivity at different relative humidity levels, aerosolization media, and efflorescence. Check it out!

Dr. Odessa Gomez & Dr. Marina Nieto led and published their #aerobiology survey in occupied public school classrooms today, validating & demonstrating novel applications for real-time bioaerosol quantitation in the built environment. You can find it here at: 10.1111/ina.12975

We are hiring! Looking for someone enthusiastic about getting out to measure ambient bioaerosols with a fantastic interdisciplinary team. And those flux measurements could include (of course) ice nucleating particles.

Thanks to our CAICE (Kathryn Moore, Tom Hill) and broadn.colostate.edu teams for supporting Saturday’s highly successful CNS Little Shop of Physics Spring Science Extravaganza, a cool and breezy, but first ever outdoor affair! @CSUAtmos Noelle C. Bryan @Marina_nieto91

Sounding balloon launch for #BACS campaign- bringing back fond memories. Team will investigate bioaerosols associated with convective storms! ⁦Paul DeMott⁩

Great first day of BACS drone and radiosonde operations! It was cold cold cold, but we got to see and make measurements of two cold pools. (Thank you to @Marina_nieto91 for getting this picture of me flying the drone with a KH wave !!!)

A couple of pics from yesterday, collecting cold pool (bio)aerosol samples for #BACS CSU Atmos Sci #mammatus #clouds #lightning #bioaerosols

#BACS closing out this week. What a great collaboration of convective storms and aerosol groups, led by Leah Grant, Russell Perkins and Betsy Stone, with the #BROADN team! ⁦Sue van den Heever⁩ ⁦@Marina_nieto91⁩ ⁦@ClaudiaMignani⁩ ⁦⁦Noelle C. Bryan⁩ #NSFfunded

Hernandez Lab's CU Boulder Engineering 🦬 students partner with @DPSNewsNow to install 800 @mySenseware air quality monitors in 10% of DPS classrooms this summer to help the district reduce student exposure and improve indoor air quality. denverite.com/2022/07/19/dps…

Fort Collins CSU has remained above 71F this morning. Pending confirmation later this evening, and assuming we don't see a rapid cool-off tonight, this would set a new *monthly* record for highest minimum temperature in August. Records at this station date back to 1893. #COwx

Possibly unpopular opinion: why are people still using PiCrust to guess the functional potential of environmental microbes? It is a WILD guess.

Airborne COVID may stay viable longer in low-humidity rooms, according to a study using mouse virus and artificial saliva. Saliva droplets become rigid at a noticeably dry 25% relative humidity, forming a glasslike protective shell. In PNAS Nexus: ow.ly/kaRY50Mue5i

Seeking REU applicants who might love interdisciplinary study of atmospheric bioaerosols! Apply soon.

VIVAS and GEMs running smoothly at the Semi-arid Grasslands Research Center in CO for the #BACS & #BROADN field campaigns! Thanks Brady Stump & Dom Aerosol Devices for your support! CSU Atmos Sci
