| Automated Weather Observing System (AWOS) stations are often grouped together with the ASOS stations, but they are not the same. Like the ASOS, the AWOS sensors primarily provide the aviation community with current weather observations. The data is also transmitted by phone lines or satellite uplinks for use by other agencies. The AWOS sites are either federally operated by the FAA or some of them are locally maintained by state agencies.[1] |
Docs:Current AWOS Data:
Historical Data:Observations from the AWOS network are saved in 1 minute intervals. The DOT provides the IEM with a monthly update of this 1 minute dataset. The 1 minute data from the previous month is uploaded to the IEM server around the first week of the month. |
