A GENERAL INFORMATION

1. Title of the dataset: Hydrological modelling datasets for streamflow modelling at the basin scale in Nigeria

2. Brief description of the research project and its aims: 
This study addresses the challenge of hydrologic modelling in data-scarce regions by exploring the use of
remotely-sensed and gridded precipitation datasets for sustainable water resource management in Nigeria.
It aims to (1) evaluate the performance of satellite-based rainfall products, (2) assess the streamflow
simulation capability of the mesoscale hydrologic model (mHM) under different calibration strategies 
(3) test the transferability of calibrated parameters to ungauged basins, and (4) simulate actual 
evapotranspiration and soil moisture using streamflow-constrained mHM parameters.

D METHODOLOGICAL INFORMATION

1. Description of methods used for collection/generation of data: Not applicable

2. Methods for processing the data: The Dataset was checked for homogeneity using Microsoft Excel and the RclimDex package in R.

3. Instrument- and/or software-specific information needed to interpret the data: 
The streamflow datasets can be interpreted using Notepad/MS Excel, while the NETCDF (.nc) files can be visualized with QGIS and Climate Data Operators (CDO command-line tools in Ubuntu operating system). The NetCDF (.nc) dataset is best accessed using CDO (Climate Data Operators) for processing and analysis.
