Access and Analyze Hourly 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 sub-daily composite web page to investigate climate/weather events.

Select variable/level. 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.
