Changelog

All notable changes to this project will be documented in this file.

[Unreleased]

[1.1.0] - 2025-11-14

Added

  • MTG-FCI instrument support with 16 spectral channels (0.444-13.30 μm)
  • load_mtg_fci() method for FCI configuration
  • Enhanced HAMlite data processing with improved file merging
  • Hurricane-centric data processing support (flavor=ifces2)
  • Comprehensive FCI test coverage

Changed

  • Extended supported instruments to include "fci" alongside "seviri" and "abi"
  • Improved ICON data input processing with better pattern matching
  • Enhanced test cleanup for notebook output files

Fixed

  • Critical bugfix: Proper handling of data together with masks in DataHandler
  • FCI channel specifications and wavelength assignments
  • HAMlite file merging operations
  • Removed dead code and unreachable conditional branches

[1.0.1b] - 2025-08-15

Added

Instrument Support

  • Support for GOES-ABI instrument alongside MSG-SEVIRI
  • New load_goes_abi() method for GOES-ABI configuration with 16 spectral channels
  • Generic load_instrument() method for instrument-agnostic loading

Code Structure and Organization

  • Parametrized tests for both SEVIRI and ABI instruments using pytest
  • Test utilities for loading predefined atmospheric profiles
  • Comprehensive test coverage for different channel configurations
  • Bash script for running both unit tests and Jupyter notebook execution

Data Handling

  • Enhanced error handling with specific exception types (e.g., KeyError, FileNotFoundError)
  • Improved filename pattern matching and sorting for data processing
  • Support for symbolic link creation for data management

Documentation

  • NumPy-style docstrings throughout the codebase
  • Enhanced API documentation structure
  • Improved function parameter documentation

Changed

Instrument Configuration

  • Refactored instrument loading with case-insensitive instrument selection
  • Renamed variables from chan_list_seviri/nchan_seviri to generic chan_list_instrument/nchan_instrument
  • Renamed load_seviri() to load_msg_seviri() for consistency
  • Updated instrument attribute naming for better clarity

Code Quality

  • Replaced bare except clauses with specific exception handling
  • Improved code modularity and separation of concerns
  • Enhanced variable naming conventions for better readability

Testing Infrastructure

  • Improved test script with sorted output and hidden path exclusion
  • Enhanced workflow testing for multiple instruments
