TL;DR

A Python library for searching, retrieving, and working with NASA's satellite ocean and climate data. It wraps NASA's ocean data web services into simple Python commands so you can pull sea surface temperatures, ocean currents, and other measurements directly into your code.

How do you spin it up?

Difficulty · moderate Time to first run · 30min

Requires creating NASA Earthdata credentials to authenticate with PO.DAAC and OceanColor web services before retrieving data.

Free to use for any purpose, including commercial use, as long as you keep the copyright notice, however, government-funded software means export control restrictions may apply.

Wtf does this do

Podaacpy is a Python library that lets you search, retrieve, and work with NASA's vast collection of ocean and climate data. Instead of manually clicking through web portals to find satellite measurements of sea surface temperatures or ocean currents, you can write a few lines of code to pull that data directly into your project. NASA's Physical Oceanography Distributed Active Archive Center (PO.DAAC) holds enormous amounts of satellite data about the oceans. This library wraps all of PO.DAAC's web services into simple Python commands. You can search for specific datasets, grab metadata about individual satellite passes, render data into image files, and download subsets of data in formats like netCDF or HDF. It also taps into NASA's OceanColor web service, so you can locate and bulk-download files from NASA's ocean data processing system. This is built for researchers, data scientists, and developers working on oceanography, climate science, or environmental monitoring. If you're building an app that tracks ocean temperatures, studying climate patterns, or need to feed satellite ocean data into a machine learning model, this library saves you from building custom integrations with NASA's APIs from scratch. The project includes Jupyter notebook examples to help you get started quickly. The library is free to use under the Apache License, though because it's government-funded software, there are export control restrictions to be aware of. It's available through standard Python package managers, making installation straightforward. The project was developed by the California Institute of Technology with NASA sponsorship, so it's an official tool rather than a community side project.

Yoink these prompts

Prompt 1
Help me install podaacpy and write a Python script that searches NASA's PO.DAAC for sea surface temperature datasets and downloads a small subset as a netCDF file.
Prompt 2
Using podaacpy, show me how to query the NASA OceanColor web service to find ocean color data files for a specific date range and region, then bulk-download them.
Prompt 3
Write a Jupyter notebook using podaacpy that retrieves ocean current satellite data, extracts metadata about each data pass, and renders a dataset preview into an image file.
Prompt 4
I have podaacpy installed, help me build a function that searches for oceanographic datasets matching specific spatial and temporal criteria, then loads the returned HDF data into a pandas DataFrame for analysis.
Prompt 5
Show me how to use podaacpy to find satellite measurements of ocean surface temperature for the Pacific Ocean last month and export the results as both netCDF and PNG image files.
