Bespoke air quality & meteorological forecasts and analyses

We generate bespoke air quality and meteorological predictions and analyses with state-of-the-art HPC software. In addition to proprietary code, we use  the latest versions of WRF-ARW (v4.5.2), CMAQ (v5.4) and other open-source apps. These simulations can cover any area worldwide and use NRT (near-real-time) data with exclusive algorithms.

Results from these bespoke simulations are distributed through the AWS Data Exchange program or directly. In addition to CSVs tabulating all fields, we also provide the general output results as netCDF files (other file formats such as GeoTIFF or GRIB2  are also available upon request).

Air quality forecasts & analyses

Current forecasts (Northeastern U.S.)

Full forecasts for this region are available from the AWS Data Exchange portal ( The forecasts cover 84 hours and represent hourly averages for over 100 species plus AQIs for PM2.5, PM1, PM10, SO2, O3, CO and NO2. The outputs are in CSV formats so that they can be imported from any system running any OS.

Air quality simulations over California and the Great Basin


Weather and air quality simulations over British Columbia and the Pacific Northwest (August 2023)

During the summer of 2023 Canadian wildfires have caused the air quality index (AQI) of several major North-American metropolitan areas to drop drastically and, in some cases, to be among the worst worldwide. These wildfires, originated by record high temperatures leading to record burned acreage, have affected not only Canada, but also the Northeastern and Great Lakes areas of the U.S. in the early summer and the Pacific Northwest and British Columbia regions in the month of August.

As an example of how internal software has been combined with CMAQ, the below snapshots show how smoke from the Canadian wildfires raised AQI (PM2.5) levels in the Vancouver and Seattle-Tacoma-Bellevue metropolitan areas on August 20th.
