As human exposure to hydroclimatic extremes increase and the number of in situ precipitation observations declines, precipitation estimates, such as those provided by the Integrated Multisatellite Retrievals for Global Precipitation Measurement (GPM) (IMERG) mission, provide a critical source of information. Here, we present a new gauge-enhanced dataset [the Climate Hazards Center IMERG with Stations (CHIMES)] designed to support global crop and hydrologic modeling and monitoring. CHIMES enhances the IMERG Late Run product using an updated Climate Hazards Center (CHC) high-resolution climatology (CHP clim ) and low-latency rain gauge observations. CHP clim  differs from other products because it incorporates long-term averages of satellite precipitation, which increases CHP clim ’s fidelity in data-sparse areas with complex terrain. This fidelity translates into performance increases in unbiased IMERG late  data, which we refer to as CHIME. This is augmented with gauge observations to produce CHIMES. The CHC’s curated rain gauge archive contains valuable contributions from many countries. There are two versions of CHIMES: preliminary and final. The final product has more copious and better-curated station data. Every pentad and month, bias-adjusted IMERG late  fields are combined with gauge observations to create pentadal and monthly CHIMES prelim  and CHIMES final . Comparisons with pentadal, high-quality gridded station data show that IMERG late  performs well ( r  = 0.75), but has some systematic biases which can be reduced. Monthly cross-validation results indicate that unbiasing increases the variance explained from 50% to 63% and decreases the mean absolute error from 48 to 39 mm month −1 . Gauge enhancement then increases the variance explained to 75%, reducing the mean absolute error to 27 mm month −1 .
