The indices offered through Climdex have been already calculated for several observational datasets. Although these source datasets are described as gridded analyses, we often offer data for the individual stations too. For the most up-to-date and quality-controlled dataset use HadEX3. If you need near-realtime data use GHCNDEX. HadEX2 is hosted here for comparison studies.
We offer time series for stations where available, whereas for gridded products we also offer average maps, trend maps and raw yearly data across any spatial domain. These products are variously available as text files, NetCDF files and image files.
Please remember to make appropriate reference to the linked publications when using these datasets.
Third-party datasets hosted by us
We also host the following datasets on climdex, but they are not part of the climdex.org project.
Australian Gridded Climate Data (AGCD) / Australian Water Availability Project (AWAP) is the Bureau of Meteorology's official dataset for climate analyses covering the variables of rainfall, temperature (maximum and minimum) as well as vapour pressure at daily and monthly timescales. The dataset provides consistent temporal and spatial analyses across Australia for each observed data variable. This accounts for spatial and temporal gaps in observations. Where possible, the gridded analysis techniques provide useful estimates in data-sparse regions such as central Australia.

BEST (Berkeley Earth Surface Temperature) provides high-resolution land and ocean time series data and gridded temperature data. Their peer-reviewed methodology incorporates more temperature observations than other available products, and often has better coverage. BEST is updated frequently on their website.

APHRODITE’s (Asian Precipitation - Highly-Resolved Observational Data Integration Towards Evaluation) gridded precipitation is a set of long-term (1951 onward) continental-scale daily products that is based on a dense network of rain-gauge data for Asia including the Himalayas, South and Southeast Asia and mountainous areas in the Middle East.
We currently offer observations over SE Asia (lat: -14.75°24°N, lon: 90.25°144.75°E)

Pre-computed Climdex indices for a number of climate models in the Coupled Model Intercomparison Project — Phase 3 (CMIP3) and Phase 5 (CMIP5) are available from Environment Canada.
