Data Products & Availability#
NASA’s PACE Mission#
Familiarize yourself with the PACE data products, their availability, and the full release notes for Version 3 reprocessing. PACE is a new and revolutionary mission, and a lot of its products are still in development, which means you won’t yet be able to work with them. Try to think of ideas for projects you could work on during the hackweek that would involve data products shown as available.
Ancillary data products used by operational algorithms can be aquired using the getanc utility from OCSSW or downloaded from the Ocean Biology DAAC directory of ancillary data products.
Relevant ESA Missions#
EarthCARE#
Consider a synergistic use of EarthCARE data from its Lidar, Radar, Multi-spectral imager or Radiometer. EarthCARE was launched in May 2024 and provides vertically resolved aerosol and cloud observations as well as radiation measurements. The EarthCARE Product Data Handbook includes links to detailed product descriptions. The satellite is in a daytime descending orbit 14:00 local time, so it crosses the PACE orbit multiple times at different locations with varying time differences. Not all data may be available for the hackweek, so please identify early on if data may be relevant for you.
TROPOMI#
Consider a synergistic use of data from the hyperspectral Sentinel-5p TROPOMI instrument, which provides observations of aerosol and cloud and trace gasses, such as CO, CH4, SO2, NO2 and HCHO. The TROPOMI sensor is in a orbit near 13:30 local time and has a wide swath, so collocated observations should be ample. TROPOMI data is provided through NASA Earthdata Cloud.
Other NASA Missions#
Potentially synergistic data products from the following missions are available on NASA’s Earthdata Cloud, with additional Landsat data available in another commercial cloud platform.
The Surface Water and Ocean Topography (SWOT) mission is a joint NASA–CNES satellite launched in December 2022 and provides wide-swath altimetry data to measure global surface water levels and ocean surface topography.
Landsat is a joint program between NASA and the U.S. Geological Survey (USGS) that collects multispectral moderate-resolution imagery (~30 m) across visible, near-infrared, and thermal bands.
The Ice, Cloud, and land Elevation Satellite 2, or ICESat-2, carries a photon-counting laser altimeter that measures the elevation of ice sheets, glaciers, sea ice, tree canopy height, ocean height, and more - all in unprecedented 3-D detail.
Earth Surface Mineral Dust Source Investigation (EMIT) is an Earth Ventures-Instrument (EVI-4) Mission to map the mineral composition of arid dust source regions via imaging spectroscopy in the visible and short-wave infrared range.
