PO.DAAC

We are pleased to announce the release of the Cyclone Global Navigation Satellite System (CYGNSS) Climate Data Record (CDR) Version 1.2 (v1.2) datasets. More information regarding the CYGNSS mission and instrumentation is available from PO.DAAC’s mission webpage. The CDR Version 1.2 collection provides a total of 3 unique datasets, each corresponding to processing Levels 1 (L1), 2 (L2) and 3 (L3), respectively.

The PO.DAAC would like to inform its users about the PO.DAAC Cloud Data Migration Timeline Update.

• The Phase 3 and 4 of our migration will be transitioned on November 14th, 2022.
• The retirement date for PO.DAAC Drive and certain legacy data access tools and services (specifically LAS, CWS, THREDDS) will be moving to March 31, 2023. After March 31, 2023, users will only be able to access PO.DAAC data through the NASA Earthdata Cloud endpoints. 

Last week, Physical Oceanography Distributed Active Archive Center (PO.DAAC) users received an email invitation from CFI Group on behalf of NASA. This message invites 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 Terra satellite is scheduled to conduct the Constellation Exit Maneuver (CEM) on October 12 and 19. All science products from observations onboard Terra satellite will be unavailable starting October 10 till October 19 and the missing data can not be recovered. 

PO.DAAC is pleased to announce the publication of new CYGNSS Level 3 Soil Moisture Version 1.0 data. The product originally covered the period from 18 March 2017 to 16 August 2020, but it is now covering data up to the present with an approximate forward production latency of 1 to 6 days (nominally under 2 days).

As PO.DAAC continues to migrate its data archive to NASA’s Earthdata Cloud, hosted in Amazon Web Services (AWS), we are pleased to announce the addition of 7 new cloud datasets. In an effort to best support the users as they begin transitioning their workflows or data access points to a cloud-based process, PO.DAAC is making the existing datasets from its archive available from and within the Earthdata Cloud as soon as they are available. Information and tutorials about how to access these datasets can be found on the Cloud Data Migration Page.

PO.DAAC is pleased to announce the dataset release of the Saildrone 2021 Arctic field campaign for the Multi-Sensor Improved SST (MISST) project, which provides surface and oceanographic measurements from two Saildrone unmanned surface vehicles (USV) during the period 6 July 2021 to 20 October 2021.

The PO.DAAC is pleased to announce the public release of the NASA Heat and Ocean Mass from Gravity ESDR (HOMaGE) monthly time series of global averaged steric sea level height anomalies (SLHA) and ocean heat content (OHC) estimates version 01 (v01), derived from the in-situ measurements.
