2024-06-17

Added

• Add CITATION.cff file to provide a citation for the repository

Changed

• Removed use of nan for fill_values to be more consistent with EMIT datasets. This means that users will have to manually assign them before plotting.
• Updated notebooks to include the new fill_value behavior, and assign them to np.nan for visualizations
• Replaced raw_spatial_crop with spatial_subset function to subset EMIT data spatially before applying orthorectification
• Fixed typos in Earthdata Search Guide

2024-03-22

Added

• geojson with plume bounding box for Visualizing Methane Plume Timeseries notebook

Changed

• Updates to instructions in Visualizing Methane Plume Timeseries notebook
• Remove horizontal lines from notebooks for web-book creation

2024-03-13

Added

• Added new Visualizing Methane Plume Timeseries notebook
• Added new Generating Methane Spectral Fingerprint notebook
• Added new tutorial_utils.py module which has functions specific to the new CH4 notebooks

Changed

• Updated setup_instructions.md to provide more up to date Python setup instructions
• Updated README.md to include new notebooks
• Added some functions to emit_tools.py to support the new methane tutorial notebooks
• Minor updates to How to Extract Area and How to Extract Points notebooks to improve visualizations

2023-12-01

Changed

• Applied automatic formatting to emit_tools.py
• Fixed GLT index adjustment in raw_spatial_crop function
• Reimplemented PointerXY stream so interactive plot from Exploring EMIT L2A Reflectance shows spectra at current cursor location

2023-11-27

Changed

Added

• How_to_find_and_access_EMIT_data Notebook - A guide for how to use earthaccess Python library to find and open/download EMIT data.

Changed

• Default behavior of emit_xarray function from emit_tools.py no longer orthorectifies, must add parameter ortho=True
• Removed ‘bands’ dimension in favor of ‘wavelengths’ for ‘radiance’ and ‘reflectance’ when using emit_xarray function from emit_tools.py
• Updated write_envi function from emit_tools.py, it should work for L1A,L1B, and L2A products.
• various other minor changes to emit_tools.py
• Updated notebooks to support changes made to emit_tools.py
• Improved RGB Image creation and brightness adjustment in Exploring_EMIT_L2A_Reflectance Tutorial
• Each notebook now uses the earthaccess python library to handle NASA Earthdata Login and downloads of needed files
• Updated setup_instructions.md and recommended python environment emit_tutorials_windows.yml
