DAACs
NASA's 12 Distributed Active Archive Centers — each curates a slice of Earth science. Bar length shows how many atlas datasets each holds.

NASA's full Earth-observation archive across all DAACs, https://www.earthdata.nasa.gov/about/data-metrics. Per-archive storage volume isn't published for most centers — NASA reports the aggregate above and only a few centers' totals (ASF ≈ 24 PB, LP DAAC ≈ 14 PB), so the chart below sizes each archive by how many of this atlas's datasets it holds, with PB shown where NASA publishes it.
