#ISES2024: Don't miss this talk at 16:15 today (Monday) in Level A-Salon 2! Dr. Xiaoying Li will present "Time- and Spatial-Resolved Personal Exposure to Particulate Matter Air Pollution: Application of Upgraded Ultrasonic Personal Aerosol Sampler (UPAS)." hubs.li/Q02TLr8l0

We’re really here at #AAAR2024! Hello from Booth #214, near the coffee station by the art completion. Stop by if you’d like to try out a UPAS!

#ISES2024: Today (Wed) we're excited to see Dr. Li present on "Advancements in Personal Exposure Samplers: Enhancing Air Pollution Assessment for Public Health" at 11:30 in Level 2 - Salon 4-5. Learn more about our wearable samplers by visiting Booth #5! hubs.li/Q02TJHd80

Source apportionment w/ UPAS PM2.5 samples today at 15:15 Level 2, Salon 4-5: "Source contributions as an outcome for evaluating the impact of household energy transitions: an example from a coal-to-heat pump heating energy transition in Beijing" #ISES2024 hubs.li/Q02TKWtB0

Sampling PM in challenging dusty environments? Today (Wed 23 Oct) at #ISES2024 from 2:45 to 4:00 PM you can see posters #972 and #973 on the new pre-cyclone impactor retrofit insert for our 1 LPM PM2.5 inlet. hubs.li/Q02TJHdn0

The day in data #ISES2024 Montreal. Sunrise (LUX sensor, pre-programmed start at 6 am sharp), walk to the conference (GPS, PM2.5, accel, temp), a bit concerning CO2 level at the poster session. Equally pleasant walk home. Ces idées qui vous ont été présentées par UPASv2.1+.

Another #ISES2024 talk featuring PM2.5 samples collected with our UPAS today (Thurs) at 10:00 in Level 2-Joyce: "The impacts of a coal-to-heat pump heating transition on indoor, outdoor, and personal PM2.5 exposure in 50 rural villages in Beijing, China" hubs.li/Q02TLdHk0

If you live in or near Alameda County, check out this link to see if you might be eligible to receive a new induction stove and participate in a study on indoor air quality!

Good morning #AAAR2024! We hope you're enjoying the conference! Our Director of Research, Jessica Tryner, will present at 8:45 this morning in Ballroom A on Personal Exposures to PM2.5 by Microenvironment among Residents of California’s Central Valley. hubs.li/Q02TLkxX0

"Future studies utilizing high-resolution data could improve the accuracy of these measurements. Heterogeneity among different studies also emphasizes the need to standardize methods for measuring PM2.5 exposure and diagnosing asthma." #weagree hubs.ly/Q02Ws8XR0

How do outdoor PM2.5 concentrations measured using UPAS compare to those measured using U.S. EPA FRMs and FEMs? Very well, actually! See data from a two-week collocation at a regulatory monitoring site in Denver in our latest blog. hubs.li/Q02WPlQC0

Did you know that you can program the time-resolved PM sensor in the UPAS v2.1 PLUS to operate on a duty cycle so the UPAS can run longer on a single battery charge? Looking for advice on selecting the best setting for your sampling application? Chec... hubs.li/Q02YyqVf0

We just posted an updated UPAS v2.1 and v2.1 PLUS User Guide. What's new? 1) An improved explanation of what happens when you start a sample from the app. 2) Advice for preparing the internal Li-ion battery for shipping or long-term storage. Download here: hubs.li/Q02YQ8fD0

We just released a new version of our astr package for reading UPAS and HHB log files into R! This version won’t throw an error if you try to read an empty sample log; it will just return a data frame with zero rows. Install from GitHub! #Rstats github.com/accsensors/astr

Published today! 100's of 24h personal & indoor PM2.5 & PM10 measurements collected at 2 LPM w/ UPAS compared to PMIs + Apex2 pumps; Spearman correlation > 0.8, normalized mean difference < 16%. All samples collected in the Central Valley w/ CSU & CCEJN. hubs.li/Q02ZfnB20

Amazing work from our CSU collaborator Shantanu Jathar and co-founder John Volckens Colorado State University groups. They're out using the patented UPAS air sampling products to gather air pollution information in LA. Products developed with funding from @NIEHS NIOSH hubs.li/Q034CsWX0

DYK - Our product pages host manuals, firmware and links to the smart phone apps. Some files are hosted on DropBox but it's not necessary to have a Dropbox account to download these files. Click on the link at the bottom of the pop-up. hubs.li/Q034D6tG0

See you soon at the Air Quality Measurement Methods and Technology Conference in Aurora, CO 4/23 - 4/25 hubs.li/Q03g9SDq0

Only 1 week left to register for the "Next-Generation Tools for Measuring Exposure to Air Pollution" hosted by the HHEAR a part of NIEHS. hubs.li/Q03gh5zR0

Wow! Do you think people are interested in understanding indoor air quality? Our project with Health Disparities to make gold standard IAQ measurements accessible to people in their homes is taking off.
