Accelerate NetCDF-4 read access

For simulating the (global) terrestrial biosphere I need time series of climate data, which is mostly provided in a 3-dimesional NetCDF file with the dimensions longitude, latitude and time. If everything is in a single file, this is often several GB large and extracting a timeseries along one position can take quiet some time, since by default NetCDF files are optimized to extract time slices. In the following I show how I speed up reading from a large NetCDF file along the time axis.
