Hi, I stumbled upon this forum via a youtube video, and thought I give it a try. I'm currently engaged in a project that involves analyzing the impact of climate change on the growth stages of wheat, known as phenology. I've gathered field samples for this study. However, a challenge I'm facing is the availability of rainfall and other meteorological data, which is limited to just one monitoring station. This limitation necessitates the need for interpolation to generate a raster dataset.

I am concerned that this approach might not sufficiently enhance the validity and reliability of my research findings. I'm wondering if there are alternative sources of rainfall data with higher resolution that could significantly bolster the credibility of my study. I came across Global Precipitation Measurement (GPM) mission but it's only 10x10km. The geographical focus of my study is Nepal. As such, I'm curious if there are any sources offering meteorological data with greater spatial resolution for the South Asian region, specifically Nepal.
