# Description
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.


### Installation
#### Conda environment setup
```
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

### Usage examples
Please check the [examples](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](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
```
