Weather Data

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.

Alaska Community Transportation Information

This data set contains information about the presence or absence of ports, airports, and other transportation infrastructure in Alaskan communities. It contains an indication of whether the community is on the road system as well.

PurpleAir Air Quality Data

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: for sensor 35151

Alaska Regions Used by Epidemiology Center

Multi-polygon files used by the ANTHC Epidemiology Center for various reporting needs. The polygons in these files roughly correspond to tribal health organizations, but many of the small THOs have been merged into larger ones.
