Update to minimum TLS requirements for https://files.airnowtech.org connectionsDear AirNow users,
Posted August 15, 2023, 11:16 (PT)

However, a small amount of users may need to update scripts if connecting to https://files.airnowtech.org using TLS 1.1 or lower. Thank you, AirNow Data Management Center |
