Download MODIS files Using PyModis

You can download MODIS files directly from NASA Earthdata. Since I want to manage everything from downloading to analyzing MODIS data in Python, I’ll use PyModis for the download process:

.

Installing Required Libraries

I will use an Anaconda virtual environment to install libraries.

conda install -c conda-forge pymodis

conda install -c conda-forge libgdal

When installing PyModis with conda, GDAL is automatically installed as a dependency. However, if it is not installed for any reason, please install GDAL manually. Additionally, installing only PyModis may not enable HDF4 file support, and you may encounter an error such as:

warnings.warn("GDAL installation has no support for HDF4, please update GDAL", ImportError)

To resolve this issue, I installed libgdal to enable HDF4 support.

I’m using downmodis from PyModis to download MODIS files.

When you access the default URL, files, they are stored in

https://e4ftl01.cr.usgs.gov/MOLA/MYD11A2.061

MOLA/

├── MYD09A1.061/

│   ├── 2002.07.04/

│   ├── 2002.07.12/

│   └── ...

To download those files by PyModis, you need to specify the location in the arguments: path and product.

In this case,

path: MOLA

product: MYD11A2.061

(where .061 is the version number)

The following code will download MYD11A2.061 files of h29v06 tile between 2024-01-01 and 2024-10-15.

from pymodis import downmodis



destination_folder = "downloads"

tiles = "h29v06"

path = "MOLA"

product= "MYD11A2.061"

today= "2024-01-01"

enddate= " 2024-10-15"



modis_downloader = downmodis.downModis(

    destinationFolder=destination_folder,

    password="your password",

    user="your username",

    tiles=tiles,

    path=path,

    product=prod,

    today=today,

    enddate=enddate,

)



modis_downloader.connect()

modis_downloader.downloadsAllDay()
