Access and Analyze Hourly Weather/Climate Time Series

This web-tool extracts time-series or sets of highest/lowest value dates from different reanalysis datasets. These dates can be saved and used in the sub-daily composite web page to investigate climate/weather events. A separate page provides time-series of daily data.

Select variable/level. You can limit the selection to a set or range of years and a particular season. There is a 30 year limit. 20CRV3 is large and <10 years is advised. Longer time periods will take a while and may time out. To save timeseries, when on the result page with time-series, select from browser file menu "Save As" or similar to a preferred filename.
