I am looking for some reanalysis data (ERA5, ERA5-land. MERRA, HAR) to calculate long term trend. Wonder if there is sufficient literature that recommend reanalysis data for trend analysis.
Nitesh Khadka : working on whole Nepal. I have already produced some result with 2m temperature from ERA5-land. Just wonder if i can support my analysis based on available literature. don't want to validate trend analysis with observation if people have already done similar stuff.
@Amrit Thapa : I don't think anyone had worked in Temperature product in Nepal. We have only worked on precipitation products, we evaluated reanalysis (MERRA) and satellite products during 2000-2018.
