Access and Analyze Daily Weather/Climate Time Series

This web-tool extracts time-series from different datasets, extracts various climate/ocean/atmosphere timeseries, and extracts dates from those time series that can be used in examining weather and climate events. These dates can be saved and used in the daily composite web page to investigate climate/weather events.

Select variable/level or pregenerated time series. Page will obtain dates that correspond to a criteria you supply. You can limit the selection to a set or range of years and a particular season.

New! You can select anomalies for gridded datasets. Climatology used is 1981-2010.

If you get a web 'time-out', try fewer years. The ERA5 is very slow.
