ACCESS to the Arctic
The ACCESS (Aerosol Counting, Composition, Extinction and Sizing System) suite of instruments is a great solution for applications like Unmanned Aerial Vehicles (UAVs), personal exposure monitoring, and any mobile platform requiring small size, low weight, and low power usage. The ACCESS line includes multiple modules for deployment individually or together as a suite. The Base Module (Model 9400) provides a compact, ruggedized PC and user interface software to control and communicate with all connected modules at the same time, making it incredibly easy to add modules in real time simply by just connecting a USB cable!

The COVID pandemic has opened our eyes to the key role airborne droplets play in transmitting diseases. Tools like the PILS and GCVI can sample large, COVID-containing droplets and other chemical species directly from the air and maintain viable virus samples for on-line analysis or off-line studies using vial collection.
What if rain patterns change so much due to climate change that some people do not get enough water to grow their food? It may be possible to seed clouds with ice nuclei or other aerosol to induce rain. Our tools (GCVI, CVI, HTDMA, SEMS) are used to determine which particles act as nuclei in real clouds, and to measure their key properties.
Maintaining stable instrument operation when large pressure and temperature changes occur during vertical profiling can be a real challenge. Instruments developed at Brechtel (SEMS, MCPC, ISO, CVI) are designed to meet airborne measurement challenges. Air flow, pressure, humidity, and temperature parameters are taken care of during research flights.
Increases in wildfire frequency have been tied to climate change, and particulate matter from wildfires can severely impact human health. Several Brechtel-developed tools (TAP, STAP) are used to measure fire plumes and assess population exposures. Mobile platforms like UAVs can easily be equipped with soot detectors to allow real-time mapping of plumes.
