[AAS07-P01] EarthCARE Data System and Product Overview for Data Users
Keywords:EarthCARE Data Product, Ground Segment, Data Distribution
EarthCARE Satellite Ground Segments Overview
This paper provides an overview of the ground system of the EarthCARE satellite, which was launched in May 2024. The ground system consists of the ground segments of the European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA), etc., shown in Figure 1, and collects, processes, archives, and distributes data from the four sensors on the EarthCARE satellite. EarthCARE has a unique feature of simultaneous observations with four sensors, which makes a complex processing chain for synergetic products. Though, we accomplished better timeliness data provision to users.
This paper provides an overview of the ground system's operations, processed products, and a guide to using the products, and introduces valuable information for potential users.
Product Overview
Table 1 lists the products provided to users by EarthCARE, which include engineering values and physical quantities from its four sensors. These products cover data on cloud vertical structure, cloud particle motion (doppler velocity), aerosol distribution and characteristics in the atmosphere, and Earth's radiation budget. Combining these data can improve future climate change predictions and aid in climate change adaptation studies.
This paper also explains the data flow, input data, processing chain, and timeline for generating these products. The products are in HDF5 format compatible with NetCDF4, viewable using tools like HDFViewer and Panoply. Data files are divided into eight frames per orbit, allowing users to quickly identify and extract necessary data based on frame ID (A, B, C, D, E, F, G and H) for specific regions like polar, equatorial, or northern hemisphere areas.
Data Utilization Guide
EarthCARE products are available from both ESA and JAXA. Using JAXA’s data distribution site “G-Portal”, users can download EarthCARE products together with JAXA’s Earth Observation data. It also provides the user support information on data usage, such as product specification formats, algorithm descriptions, product update histories and usage caveats according to version, data unavailable periods (missing products due to calibration operation, special operation etc.), and links to introductions to tools for using the data, to help users use the data effectively.
