ABSTRACT:

This resource includes 30-minute GPM IMERG data downloaded for central Nepal, saved in a MATLAB variable with an accompanying function to retrieve a timeseries from coordinates, as well as CSV files with GPM IMERG rainfall generated for each DHM, ICIMOD, and FRES station in the area of interest.

This resource also includes a composite "scaled" rainfall product which uses the DHM, ICIMOD, and FRES gauges to correct the magnitude of the unprocessed GPM IMERG data.

Data are compiled and interpreted for the 2010-2022 time period.

ABSTRACT:

This collection contains 3 sources of rainfall data covering Central Nepal, and especially the area around the Melamchi Khola. These data were collected and assembled as part of the Nepal FRES project.

The first resource contains precipitation data from tipping-bucket gauges installed in and around Melamchi Valley. The first gauges were installed beginning in 2022. Others were installed later. Details are in the readme with the resources. Rainfall data collection is ongoing as of 2026.

The second resource contains private daily and hourly rainfall data purchased from the Nepal Department of Hydrology and Meteorology (DHM) and the International Centre for Integrated MOuntain Development (ICIMOD).

The third resource contains public 30-minute satellite rainfall data (GPM IMERG) downloaded for the entirety of central Nepal from 2010-2022. This third resource also contains a "scaled" rainfall product which scaleds the 30 minute GPM IMERG timeseries to match daily rainfall totals from DHM, ICIMOD, and FRES stations.
