Dears,
I would like to spatially interpolate gridded (10X10km) hourly temperature data to a finer spatial grid (e.g. 5X5km). I am talking about 1 year of data (thus 8760 hourly temperatures) for each point of my grid (e.g. 100,000 data points).
I am using QGIS for the interpolation. First, I have issues in uploading the .txt file in QGIS. The QGIS crashes as soon as I am trying to upload a .txt file with 8762 coloumns (e.g. lon, lat, T1, T2, T3, ..., T8760). Is there a way to easily uplodad and work on heavy files in QGIS?
Secondly, I have problems with the interpolation. Using for instance IDW, what I get is a raster for each hourly tempererature time-step. On this regard, I have two questions:
1 - Is there a way to automate the procedure using QGIS? Thus, automatically obtaining hourly temperature data interpolated to my finer grid?
2 - Are there other easier procedures/software to obtain the interpolation to a finer grid?
Thanks for your support.
Best,
Giorgio
