Web-based Reanalyses Intercomparison Tools (WRIT)
PSD is creating a set of web-based reanalyses comparison tools. Our first tool is a monthly plotting page that allows users to plot from various reanalyses. Plots include means, anomalies and climatologies. Users can also difference the various reanalyses for all three types of statistics (for any overlapping date in the reanalyses). Composites (averaging multiple dates) are available as well. We will add the ability to use our available climate timeseries (e.g. PNA) or your own time series to composite on.
Our second tool is a monthly timeseries extractor/analyzer. It extracts timeseries at specified lat/lon or lat/lon ranges and either plots the data, plots differences between reanalyses or does other types of analyses. We plan to add climate index timeseries to the page as well for comparison with the gridded reanalyses data. We may also add observational datasets.
Current Web Tools
Future Products
We are exploring the feasibility of various tools. The features we hope to have are:
- Daily time scale composites
- Sub-Daily composites
- Temporal correlations of variables with index time series
- Spatial correlation comparing different reanalyses
- Creation and comparison of index timeseries such as the PNA from the various reanalyses
We welcome more suggestions!!
