Validation of NOAA CPC_RFE2.0 satellite-based rainfall estimates in the central himalayas

This publication addresses the vulnerability of the Hindu Kush Himalayan region to many types of hazards, and especially to floods and landslides. As part of a project aimed at strengthening regional cooperation in flood forecasting and information exchange, and building capacity among partner institutions, it presents the findings of a detailed assessment of the accuracy of NOAA CPC_RFE2.0 satellite rainfall estimates over the central Himalayas of Nepal. The results indicate that the overall spatial detection and trends are good, and with appropriate bias correction.

The report is divided into five chapters, followed by an annex: (i) the first chapter introduces the project and its objectives; (ii) chapter two describes the study area and data used for the study; (iii) chapter three presents the procedures and techniques for validating NOAA’s SRE products in the study area, including data preparation, data quality control, data conversion, methods of interpolation, and the statistical measures used to compare the satellite estimates with rain-gauge data; (iv) chapter four presents the results and discussion; and (v) chapter five summarizes the conclusions and suggests a way forward.
