Advanced Himawari Imager (AHI) data with Satpy

pythia ncar

This notebook is developed during the pythia cook-off at NCAR Mesa-Lab Boulder Colorado, June 12-14, 2024

Participants in the workshop event have the chance to practice collaborative problem-solving and hands-on learning in the field of Python programming.

This notebook is part of the Breakout Topic: Geostationary on AWS, lead by Jorge Humberto Bravo Mendez jbravo2@stevens.edu, from Stevens Institute of Technology

Advanced Himawari Imager (AHI) data with Satpy

Using Satpy to read and Advanced Baseline Imager (ABI) data from GOES-R satellites. Here’s a step-by-step guide:

Imports

import warnings
warnings.filterwarnings('ignore')
warnings.simplefilter('ignore', SyntaxWarning)

from satpy.scene import Scene
from satpy.utils import debug_on

from datetime import datetime

from glob import glob

Starting to create satpy scenes

sat_files = glob("input/HI9_AHI_L1b_JP/*")
sat_files
