Description

This dataset provides hourly ocean bottom pressure measurements at the North Pole from the Arctic Bottom Pressure Recorder - Follow On (ABPR-FO) from August 2022 to August 2023. Based around a Paroscientific Digiquartz pressure sensor, the ABPR-FO was designed and powered to collect and transmit data which was then collected, quality-controlled and updated at PO.DAAC on a yearly basis. The full time series is provided as a single netCDF file, and reports both bottom pressure (reported as liquid water equivalent thickness) and temperature. This dataset aims to serve as in situ validation for GRACE-FO data products in the central Arctic. This project is funded by NASA’s GRACE and GRACE-FO Science Team and supported by PONANT Science.

Variables

Variables are a set of physical properties whose values determine the characteristics or behavior of something. For example, temperature and pressure are variables of the atmosphere. Parameters and variables can be used interchangeably. Variable level attributes provide individual information for each variable.

The Name in this table is the variable name. Fill value indicates missing or undefined data points in a variable. Valid range is the range of values the variable can store. Scale factor is used to increase or decrease the size of an object and can be used to correct for distortion. For questions on a specific variable, please use the Earthdata Forum.
