This repository does NASA MODIS data aggregation from level 2 to level 3 in a flexible and parallel approach. Please check documents in examples folder to see examples on how to use our software.

conda create -n MODIS_Aggregation -c conda-forge python=3.7 libnetcdf netCDF4 h5py

>> git clone https://github.com/big-data-lab-umbc/MODIS_Aggregation.git
>> cd MODIS_Aggregation
>> python setup.py install

The code is tested with Python 3.7

Please check the examples folder to see sample codes to import the library and use its functions for specific aggregation requirements. The examples mainly demonstrate how to conduct local execution, Dask-based distributed execution and MPI-based distributed execution. Besides these core usage examples, we also show examples for result comparison and service based deployment.

Before running the aggregation example, please read the README.md in the examples folder for the instruction on downloading the Level-2 input data.

To run the aggregation example in local environment:

>> cd examples/local_execution
>> sh MODIS_Aggregation_Local_Commands.sh
