City temperature database archive download

Whether you need historical weather by ZIP Code or climate data by address, our vast historical weather data archive has the data that you seek. As the response to a single query, our engine can combine hundreds of local weather station records to produce a single, coherent weather report. This ensures global coverage in every city and address your project may need. Our weather forecasts offer hourly detail and daily summaries for a full days. For projects that need even longer-range forecasts, our climate-based forecasts provide weather norms and patterns for any day of the year.

Download weather variables, such as temperature, wind, cloud cover, precipitation and many others in hourly resolution as CSV, or explore the datasets online. Any place worldwide is available in hourly intervals without gaps since Archived weather simulations are assembled to continuous time series. Historical data are the first step to correlate past events and optimize your current and future business.

All weather variables are available for any place on Earth and at various different altitude levels, independent of measurement stations. We calculate global weather models as well as local high resolution models for Europe, North and South America, and most parts of Asia and Africa. Intensive verification and validation improves our weather models beyond the quality and availability of historic weather measurement data.

The interface provides access to the proprietary global numerical weather model NEMS, the ERA5 re-analysis model, and to local high-resolution weather models for many areas. All data can be downloaded for the selected locations for a period of more than 40 years. Access remains active for 1 year after purchase and includes daily updates of the datasets. All time series are consistent and gap-free, whereas measurements are often not available for the selected place, or unavailable for certain time periods or contain invalid data.

Analysis with insufficient and inconsistent data makes results unreliable and massively increases the processing effort.

Data can be interactively analysed on the web, and also downloaded as CSV files. Common evaluations such as year comparison, GDD calculation, frequency analysis, crop risk evaluations, or wind roses, are built-in.

Downloaded CSV files can easily be imported into other professional applications. Weather variables information Temperature 2m and relative humidity 2m : Comparable to measurements at 2 meters above ground. Pressure: Atmospheric air pressure adjusted to mean sea level as most commonly used for weather reports. The local pressure varies with altitude. Locations at higher elevation have a lower local atmospheric pressure. Precipitation amount: Total precipitation amount including rain, convective precipitation and snow.

Snowfall amount: Fraction of total precipitation that falls as snow and is converted to cm instead of mm. Low, mid, high cloud cover: Cloud cover at different altitudes. High clouds km like Cirrus, are less significant for total cloud cover than mid clouds km like Alto-Cumulus and Alto-Stratus, or low clouds below 4 km , like Stratus, Cumulus and fog.

Solar radiation: Global radiation diffuse and direct on a horizontal plain given in Watt per square meter. Wind speed: Hourly average wind speeds at given altitude levels e.

Units can be selected. Wind gusts: Short term wind speed turbulence in an hour. Gusts are maximum measurable wind speed and indicate the level of turbulence. They are mostly higher than regular wind speeds. Select all.

Connect and share knowledge within a single location that is structured and easy to search. I am looking for historical hourly temperature data from many cities in the US what other data sources are there except wunderground? I am not mentioning a specific US city because I need data from as many cities in the US as possible that meet my requirements.

I am working on a big project of forecasting and I want to see the spatial deviations with in many large cities in the US. And Wunderground already archives them, so it's a matter of selecting and using those, rather than the Wunderground data from their own source, the collection of personal weather stations. Customers can also order most of these data as certified hard copies for legal use. Order Status.
