If you're looking for raw data, you can find measurements from NASA's earth observation missions here: https://earthdata.nasa.gov/ https://earthdata.nasa.gov/ NASA's Worldview application presents the data as overlays on maps of the Earth and it lets you scroll backward in time from the start of the missions (around 2000 or so) up to near real time (a few hours old). If you want to make sense of the scientific data, you'll still need to put some work into understanding what the instruments are measuring: https://worldview.earthdata.nasa.gov/ https://worldview.earthdata.nasa.gov/
