Living Planet Symposium 2019
David Moroni representing PO.DAAC at the European Space Agency’s 2019 Living Planet Symposium in Italy this week from May13 - 17, 2019.
Data in Action: Ocean impacts of Cyclone Idai
Cyclone Idai was a major tropical storm that made landfall in Africa, an unusual case, that had unfortunate consequences in Mozambique, Zimbabwe and Malawi with severe flooding and loss of life.
Dataset Update: Complete historical records of GRACE Level-2 RL06 datasets now available
2019-04-10
The PO.DAAC is pleased to announce that the complete historical data records of GRACE Level 2 Release 06 (RL06) datasets are available. The complete records include all available historical data from April 2002 to June 2017.

SPURS2 Field Campaign First Dataset Release
April 9, 2019
The SPURS (Salinity Processes in the Upper Ocean Regional Study) project is a NASA-funded oceanographic process study and associated field program that aim to elucidate key mechanisms responsible for near-surface salinity variations in the oceans. SPURS employs a suite of state-of-the-art in-situ sampling technologies that, combined with remotely sensed salinity fields from the Aquarius/SAC-D, SMAP and SMOS satellites, provide a detailed characterization of salinity structure over a continuum of spatio-temporal scales. While SPURS-1 focused on the salinity maximum region of the sub-tropical N. Atlantic, SPURS-2 concentrated on the dynamic and seasonally variable, rainfall dominated region of the eastern tropical Pacific centered at 10N, 125W. The SPURS-2 campaign involved two month-long cruises by the R/V Revelle in August 2016 and October 2017 combined with complementary sampling on a more continuous basis over this period by the schooner Lady Amber.
This initial SPURS-2 data release includes the first seven of what will ultimately be a total of twenty eight in-situ datasets produced during the SPURS-2 field campaign that will be archived/distributed by the PO.DAAC. Datasets comprising this release include: vertical profile data from lowered Conductivity, Temperature, Density (CTD), Expendable Bathythermograph (XBT) and ARGO profiling float instruments, water column current velocity profiles from shipborne Acoustic Doppler Current Profile (ADCP), along-track multivariate sensor measurements from Saildrone, WAMOS wave radar data, and precipitation imagery data from the SEA-POL rain radar. Sample data plots of six of these datasets are illustrated in figure 1 below.
SPURS-2 Resources at PO.DAAC:
Figure 1: A) SEA-POL rain accumulation imagery data, B) XBT temperature profile time series plot, C) lowered CTD station salinity profile plot, D) ARGO float vertical salinity profile, E & F) WAMOS along-track WAMOS mean wave period trajectory and time series plots, G & H) ADCP u-current velocity trajectory and vertical profile series, and I & J) surface temperature trajectory and times series from Saildrone.

Warning: VIIRS_NPP-JPL-L2P-v2016.0 dataset degradation
2019-02-19
Unexpected errors have been discovered recently in the VIIRS_NPP-JPL-L2P-v2016.0 dataset since September 15th, 2018. We advise the users to use the post Sept. data with extra caution. Immediate efforts have been made by the data producer (NASA OB.DAAC) to resolve the issues. The corrected data granules will be available in a couple of weeks.

REMINDER - PO.DAAC FTP RETIREMENT: Important Information for Users
2019-02-13
Last year, we informed our users (https://podaac.jpl.nasa.gov/announcements/2018-06-05_Deprecation_of_FTP_at_PO.DAAC) that NASA was in the process of deprecating the use of the FTP protocol for data and information access, and that PO.DAAC was offering PO.DAAC Drive as a robust FTP alternative for browsing and retrieving data at PO.DAAC.

Cold Wake Signatures from 2018 Atlantic Hurricanes
Evolution of the NASA Multi-Scale Ultra-High Resolution (MUR) sea surface temperature (SST) response to Hurricanes Florence, Helene and Isaac of 2018. It is common to observe trails of cooler water, or cold wakes, along hurricane tracks as a result of wind-induced mixing and turbulence that brings cold waters at depth to the surface. The cold wakes associated with Florence, Helene, and Isaac are clearly observed as waters approximately 2°C cooler from normal along the hurricane track that persisted for several days. (MUR SST DOI: 10.5067/GHGMR-4FJ04).
