Super-resolution framework

Getting Started

  • Download the relevant datasets from the following links and save them in respective subdirectories under the data directory.
    • Link for the mean flow dataset. Individual cases to be saved as data/kepsilon, data/komega etc.
    • Link for the NOAA Optimal SST dataset. To be saved in data/noaa/.
    • Link for the global soil moisture dataset. To be saved in data/sm/.
  • The first run for each example generates relevant tessellated fields and saves them in subdirectories under data/npy/.

Dependencies

  • Python 3.x
  • Tensorflow TF 2.x. Install either the CPU or the GPU version depending on available resources.
  • A list of all the dependencies are provided in the requirements file.

Executing program

  • Training and evaluation for the mean flow dataset can be performed using examples/Mean_Flow/mf.py. The script is set up to parse various arguments during the execution call which typically looks like python mf.py 'unet-kepsilon-PHLL_case_0p5 PHLL_case_0p8 PHLL_case_1p0 PHLL_case_1p2 BUMP_h20 BUMP_h26 BUMP_h31 BUMP_h38 CNDV_12600-Ux Uy-PHLL_case_1p5 BUMP_h42 CNDV_20580-Ux Uy-train'
  • Training and evaluation for the NOAA SST dataset can be performed using examples/Sea_Surface_Temperature/sst.py.
  • Training and evaluation for the soil moisture dataset can be performed using examples/Soil_Moisture/soilmoisture.py.
