The PACE Spacecraft Housekeeping Telemetry collection contains Level-0 engineering and navigation telemetry data from the NASA Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission. The collection includes spacecraft and instrument housekeeping packets, spacecraft attitude quaternions, angular rates, orbit position and velocity vectors, and associated processing control metadata, provided in NetCDF4 format. These data describe spacecraft and instrument status, health, timing, and orientation and are essential for mission operations, calibration, geolocation, and quality assessment of higher-level PACE science products from OCI, HARP2, and SPEXone. The housekeeping telemetry supports engineering analysis and science data processing workflows and is archived and distributed by NASA’s Ocean Biology Distributed Active Archive Center (OB.DAAC) for community access and long-term preservation.
