fierpy
Python implementation of the Forecasting Inundation Extents using REOF method
Based off of the methods from Chang et al., 2020

Example use
import xarray as xr
import fierpy
# read sentinel1 time series imagery
ds = xr.open_dataset("sentine1.nc")
# apply rotated eof process
reof_ds = fierpy.reof(ds.VV,n_modes=4)
# get streamflow data from GeoGLOWS
# select the days we have observations
lat,lon = 11.7122,104.9653
q = fierpy.get_streamflow(lat,lon)
q_sel = fierpy.match_dates(q,ds.time)
# apply polynomial to different modes to find best stats
fit_test = fierpy.find_fits(reof_ds,q_sel,ds)
