\ud83d\udd0eThe Science of Seeing More<\/em><\/h2>\n

Remote sensing fans, get ready for NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission<\/strong>. PACE provides the world\u2019s first global, daily, publicly available<\/strong> hyperspectral satellite data covering 350\u2013890 nm wavelengths<\/strong> (that\u2019s the ultraviolet<\/strong>, visible<\/strong>, and near-infrared<\/strong> range) with 1.2 km2<\/sup> spatial resolution! This graduates us to a higher spectral resolution; in traditional imagery like Landsat and Sentinel, we are used to working with less than 15 visible and near infrared wavelengths. With PACE we now can use hundreds<\/em><\/strong> of wavelengths on the electromagnetic spectrum, a spectral upgrade that lets us see aerosols, ocean particles and phytoplankton, land vegetation, and clouds in a whole new light! Seeing the ocean from space has always been a challenge as seawater reflects little light, but PACE\u2019s advanced optics capture both bright and dark targets, revealing hyperspectral details across land, ocean, and atmosphere. This mission is reshaping how we study our planet\u2019s interconnected systems.<\/p>\n

PACE Derived Products\ud83c\udf0a\ud83c\udf3f\ud83c\udf2b\ufe0f<\/strong><\/strong>: 10 Ready to Use Image Services in ArcGIS Living Atlas<\/h2>\n

First, we’ll focus on scientifically derived products<\/strong> scientifically derived PACE products including ocean chlorophyll-a, vegetation indices, and aerosol optical depth. NASA Earthdata\u2019s Geographic Information System (EGIS)<\/a> team has released 10 analysis-ready PACE image services<\/strong> directly into the ArcGIS Living Atlas<\/strong>, giving you instant access to visualize, analyze, and compare environmental changes in both ArcGIS Pro and ArcGIS Online. These services are global, time-enabled and cover Earth’s land, ocean, and atmosphere. No downloads required!<\/strong> Interact with all 10 PACE image services directly in this Experience Builder application <\/a>or NASA’s Plankton Aerosol Cloud ocean Ecosystem (PACE) Mission Web Map<\/a>. Jump into PACE data action by navigating layers, toggling datasets, playing the time slider, and zooming to a location. To choose the right image service for you,\u00a0check out NASA’s PACE content list<\/a> for product descriptions, source information, and scientific context.<\/p>\n

To directly download derived products, such as chlorophyll-a concentration<\/a>, visit NASA Earthdata<\/a>\u00a0(be sure you have an Earthdata account!<\/a>). While the 10 PACE ArcGIS image services provide ready-to-use access to key variables, NASA offers even more derived products at several time and space resolutions<\/strong>; check out the Data Products Overview<\/a> list and Data Product Table<\/a>. These datasets are analysis-ready and can be added directly into ArcGIS Pro<\/strong>, giving you more flexibility to work with data outside the pre-configured image services.<\/p>\n

We’ve looked at scientifically derived PACE products, now let’s transition to the hyperspectral reflectance data<\/strong> itself. Are you a user wanting to work beyond the derived PACE data products to perform advanced, custom hyperspectral analysis?<\/strong> With access to hundreds of spectral bands, you can investigate spectral features and build your own indices!<\/p>\n
