National Aeronautics and Space Administration
GovernmentNASA operates Earth observation satellites that collect continuous data on climate, weather, atmosphere, and land use. Beyond space exploration, the agency publishes massive datasets including satellite imagery, atmospheric measurements, and oceanographic information. Their Earth Observing System provides free access to decades of environmental data, making it a critical resource for climate research, disaster response, and environmental monitoring. NASA also maintains the Global Imagery Browse Services and distributes data through multiple public portals including SEDAC and DAAC repositories.
Pinned datasets
GISTEMP Zonal Temperature Anomalies
Temperature doesn't warm evenly. The Arctic heats up much faster than the equator, and the Northern Hemisphere differs from the Southern. This dataset shows exactly how much warmer (or cooler) each latitude band has gotten compared to the mid-20th century baseline. It's the data behind headlines about polar amplification and regional climate differences.
GISTEMP Global Temperature
Want to know if the planet is actually warming? This is the data that settles the argument. NASA combines temperature readings from weather stations around the world and ocean buoys to calculate how much hotter or colder each month was compared to a standard baseline from the 1950s. If the number is positive, that month was warmer than average. If negative, it was cooler. It goes all the way back to 1880, so you can see the long-term trend. This is one of the main datasets climate scientists point to when they talk about global warming.
