Featured Products

Latin American Flood and Drought Monitor

The Latin American Flood and Drought Monitor is a powerful and versatile web-based tool that can monitor and predict periods of drought, flooding or other extreme events by providing real-time data for more meteorological and hydrological variables,  allowing users to visualize and interact with region-specific data.

African Flood and Drought Monitor

The African Flood and Drought Monitor (AFDM) is a powerful and versatile web-based tool that can monitor and predict periods of flooding and drought by providing up-to-date data for more than 20 different meteorological and hydrological variables, as well as allowing the user to visualize and download region-specific data.

Acclimatise PCA Global Drought Risk

The PCA drought risk product is based on state-of-the-art global hydrological modeling and climate model data. This map-based product covers both baseline (‘historic’) and future droughts of various durations (1-3 months, 4-6 months, 7-12 months and 12 months +). The drought maps are presented as either ‘return periods’ (years) or ‘annual frequencies’ (%). Acclimatise has been used by banks in the pilot project to analyze drought risk to borrowers in the agriculture sector.

Multi-Source Weighted-Ensemble Precipitation (MSWEP)

Multi-Source Weighted-Ensemble Precipitation (MSWEP) is a unique gridded precipitation dataset spanning 1979–2017. MSWEP is groundbreaking in its full global coverage (all land and oceans), high spatial (0.1°) and temporal (3 hourly) resolution and merging of precipitation estimates based on rain gauges (WorldClim, GHCN-D, GSOD, GPCC, and others), satellites (CMORPH, GridSat, GSMaP, and TMPA 3B42RT), and models (ERA-Interim and JRA-55).

Multi-Source Weighted-Ensemble Precipitation (MSWEP)

MSWEP-NRT is the near real-time (NRT) vari­ant of the his­toric Mul­ti-Source Weight­ed-Ensem­ble Pre­cip­i­ta­tion dataset. The prod­uct pro­vides pre­cip­i­ta­tion esti­mates (3-hourly tem­po­ral and 0.1° spa­tial res­o­lu­tion) for the entire globe using a nov­el algo­rithm that opti­mal­ly merges pre­cip­i­ta­tion esti­mates from a broad range of data sources.

Global NRT Flood Monitor

The NFMS developed by Princeton Climate Analytics (PCA) provides near real-time, multi-scale mapping of surface water inundation to support global, regional and local flood risk monitoring, mitigation and damage assessment, and water management. Potential users of these data include government agencies, institutes, insurance companies and individuals.

High Res Global Monitor

The next step in PCA’s Flood and Drought Monitoring , the High-Resolution Global Monitor will combine data from the African, Latin American, and North American Monitors with other data sources to create a seamless global product at a 5km resolution. Updates will occur on a 3-hourly basis via the Princeton Hydrological Engine (PHE).

Lake Chad Monitor

A demonstration regional flood and drought monitoring system for the Lake Chad Basin (CHAD-FDM) has been developed based on the continental African Flood and Drought Monitor (AFDM, Sheffield et al., 2014). The regional monitor currently has basic capabilities to show historic surface water conditions for the basin, at 5km, daily resolution for the period 1990-2016. There is a need to develop this into an operational system that has the capabilities to monitor in real-time and provide forecasts at short-term to seasonal time scales, and includes local data.

Chile Monitor


The Chile Monitor is a high resolution flood and drought monitoring and forecasting tool with a resolution of 5km. Users will be able to visualize precipitation, streamflow, and other meteorological data from historical, near-real-time, and forecast datasets. Streamflow, especially, is a main focus of the Chile Monitor, and it will be able to closely follow high and low flows, flow accumulation, and timing of melt peak. Finally, the Chile Monitor will also incorporate at least five CMIP5 climate change scenarios for added insights into temperature and precipitation changes in different RCP trajectories.

IDB Hydro-BID Platform

PCA’s IDB Hydro-BID Platform, currently in development version 1.1, is a capable, reliable, and easy-to-use climate data tool for scientists and hydrologists with a focus on Latin America.
