Blue and green denote lower concentrations and orange and red areas denote higher concentrations, ranging from 1e+15 to 5e+15 molecules per square centimeter, respectively. || ", "release_date": "2014-06-26T06:00:00-04:00", "update_date": "2023-05-03T13:50:48.315398-04:00", "main_image": { "id": 454136, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011500/a011576/atlanta_0507_no_roads_states.jpg", "filename": "atlanta_0507_no_roads_states.jpg", "media_type": "Image", "alt_text": "Atlanta: spring-summer average from 2005-2007.", "width": 960, "height": 1080, "pixels": 1036800 } } ], "sources": [], "products": [], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
