The LEO Network data portal crawls daily weather data from the NOAA GHCN data source. The LEO Data Portal can be configured to crawl any set of weather stations that are in the GHCN database. In practice, we crawl ones that are in Alaska or elsewhere in the Arctic and that are currently online, meaning that they are collecting new data.
This data file represents all of the stations currently being crawled on a daily basis. You can get it in three formats:
Daily data for individual weather stations is available at URLs similar to this one:
(Replace the last part of the URL with the weather station that you are interested in.)
Individual data files contain information on minimum and maximum observed temperature in Fahrenheit for a given day, as well as precipitation and snowfall in inches. For some stations, snow depth in inches is also recorded.
We perform hourly crawls of Purple Air data to retrieve the latest readings from a select set of approximately 200 sensors in Alaska and nearby. We retrieve hourly data for PM 2.5 readings, which we then convert to EPA AQI values.
Map of sensors. Search or click on a sensor to download historical data for that sensor.
Historical data for any given sensor may be downloaded in CSV format via a URL that includes the sensor index. For example: https://tribalhealthnetwork.org/purpleair/data/35151 for sensor 35151

Dataset and dashboard generated from State of Alaska Veterinarian website tracking positive cases of avian influenza.
Dataset based on reports of unusual bird behavior during 2022, shared with ANTHC by U.S. Fish and Wildlife Service.
Datasets are built by scraping data from State of Alaska epi-bulletins about reportable infectious diseases. Disease counts are tracked annually. Note that these data sets do not include all reportable infectious diseases. They are limited only to ones relevant in a One Health context.
Datasets are built from the annual infectious disease reports from AK Department of Epidemiology, available here: https://health.alaska.gov/dph/Epi/Pages/bulletins/default.aspx
