The National Oceanic and Atmospheric Administration provides records of past weather and climate data through Climate Data Online, available on the NOAA website. The AccuWeather Premium website also provides daily rainfall and snowfall totals as far back as 1992.
Visitors can access the CDO for free to acquire historical records of daily, monthly, seasonal and yearly measurements of rainfall. People may also order hard copies of these records from the NOAA for legal purposes. AccuWeather offers a free 15-day trial for access to historical rainfall records as of 2015, but further access requires a paid account.
The CDO accommodates searches for historical records by the name of the weather station, a ZIP code, city, state, county or country.
