NOAA Reanalysis Intercomparing Tool

A web-based climate diagnostics tool for comparing multiple global atmospheric reanalysis datasets to evaluate historical climate conditions and atmospheric circulation patterns.

Supports climate research, historical analysis, and verification of seasonal forecasting methodologies used by NMHSs.

Supports capacity development in atmospheric diagnostics and evaluation of climate datasets.

Developer: NOAA Physical Sciences Laboratory
Stage Of Maturity: Mature

Strengths

  • Facilitates comparison across reanalysis datasets
  • Supports climate diagnostics
  • Useful for validation and research
  • Broad selection of atmospheric variables

Weaknesses

  • Not a forecasting platform
  • Not intended for operational decision support
  • Requires technical understanding of atmospheric science

Synergies

  • Uses multiple global reanalysis datasets available through Copernicus CDS.
  • Complements historical climate analysis in KNMI Climate Explorer.
  • Supports evaluation of climate datasets used in CORDEX South Asia.
  • Can support verification of forecasting systems.
