PyMHW: A Python Package for Marine Heatwave Detection and Analysis

Attention! Still under construction!!

pymhw is a Python package to calculate marine heatwaves (MHW) based on sea surface temperature (SST) data.


Please, cite this DOI and check new releases.

Installation

You can install the package using pip:
pip install git+https://github.com/andrebelem/pymhw.git

Usage

import pandas as pd
import pymhw

# Assuming df and df_clima are your already loaded DataFrames
df2 = pymhw.detect_MHW(df, df_clima)
mhw_periods = pymhw.calculate_mhw_periods(df2)

print(mhw_periods) #<-- results are condensated in a dataframe

Example Analysis

There is an example (Test_Marine_Heat_Waves_detection.ipynb) with an overview of how to use the pymhw package for analyzing marine heatwaves.

Key Steps:

• Detect MHWs: Use the detect_MHW function to preprocess and detect potential MHW events in your SST data.
• Calculate MHW Periods: Use the calculate_mhw_periods function to identify and categorize MHW periods based on their intensity.
• Visualizing MHWs: Some example of graphics you can use (on the .ipynb file).

Future code:

• Include subsurface analysis and more statistics
• Create a MHW index or impact index
• Perform wavelet analysis on MHW index
