PO.DAAC

Last week, Physical Oceanography Distributed Active Archive Center (PO.DAAC) users received an email invitation from CFI Group on behalf of NASA. This message will ask you to participate in a web-based survey of NASA Earth Science data and services. PO.DAAC is one of twelve NASA Earth Observing System Data and Information System (EOSDIS) data centers evaluated by this survey. The purpose of this survey is to help PO.DAAC assess customer satisfaction and improve future services.

The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is pleased to announce the availability of new Level-2 and 3 datasets from the Combined Active-Passive (CAP) Algorithm applied to the version 5.0, end of mission Aquarius/SAC-D data.

Last Friday, on 21 September 2018, we had announced the public release of the  CYGNSS Version 2.1 dataset. More information on that release is available here: https://podaac.jpl.nasa.gov/announcements/2018-09-21_CYGNSS_Public_Science_Data_Release_Version_2.1

The PO.DAAC is pleased to announce the public release of the Cyclone Global Navigation Satellite System (CYGNSS) Version 2.1 Science Data Record. CYGNSS is a NASA Earth System Science Pathfinder Mission collecting the first frequent space‐based measurements of ocean surface wind speeds in the inner core of tropical cyclones.

The PO.DAAC is pleased to announce the public release of the GRACE Level-2 Release 06 (RL06) datasets from the German Research Centre for Geosciences (GFZ).  These datasets complete the release of GRACE Level-2 RL06 products (see Release announcement on July, 16, 2018).  The RL06 version of GRACE Level-2 has made several significant improvements and updates from the current RL05, including updated background force models and improved parameterizations.
