earthaccess is a community-driven python library that streamlines access to NASA's Earth science data and supports researchers who are migrating their workflows to the cloud. 

This library handles Earthdata Login authentication, allows users to search data in the Common Metadata Repository, and download data no matter if you are downloading data from in the cloud or on-premises.

Three-panel figure comparing EMIT and PACE OCI observations over a wildfire region in southeastern Australia. The left panel shows a high-resolution stretched RGB EMIT image with detailed terrain, vegetation, burn scars, and surrounding agricultural fields. The center panel displays surface reflectance spectra for a selected location (approximately 142.3°E, 37.0°S), comparing EMIT pre-fire and post-fire observations (solid green and orange lines) with corresponding PACE OCI pre-fire and post-fire observatio

Processing PACE and EMIT Data

This tutorial will demonstrate how to preprocess the EMIT and PACE reflectance data so that they can be used together to investigate science questions. Using the emit_tools and pace_tools modules, the data are orthorectified, geolocated, merged where needed, and resampled onto a common grid, enabling direct comparison of observations from the two sensors.

The folium map above highlights the differences in the observation footprints of the two instruments while clearly showing where each EMIT granule falls within its corresponding PACE OCI granule. For the observations on November 14, 2024, the EMIT granules are located near the center of the PACE OCI granule and collectively cover the full extent of the park. In contrast, most of the other EMIT granules lie near the edges of their paired OCI granules.

ASTER Level 2 Surface Kinetic Temperature (AST_08) over Kīlauea Crater, Hawaii, acquired on 2025-08-09 at 07:30:32 UTC. The image shows a semi-transparent thermal overlay on an Esri satellite basemap. A concentrated hotspot of temperatures exceeding 100°C is visible near the center of the crater floor, displayed in deep red, surrounded by a gradient of orange and yellow tones indicating elevated but cooler surface temperatures. The surrounding terrain shows ambient temperatures near 0°C. The spatial ex
