PO.DAAC Alert: Interruption of MODIS data (Monday - Thursday) |
|
The provider of all MODIS data, MODAPS will be down from Monday, April 20, 5pm through Thursday, April 23, 12pm while upgrades are made to the electrical power at their facility. There will be no MODIS data and consequently no GHRSST data during this time.
We apologize for the late notice. |

PO.DAAC Alert: MODIS DATA OUTAGE |
|
There will be a power outage at the NASA Goddard MODIS Facility from Wednesday, February 18, 5pm (EST) through Friday, February 20, 3pm (EST). During this time there will be no MODIS level 0 data and hence no MODIS higher level products.
The affected data products will include all PODAAC Level 3 MODIS, all GHRSST L2P products and any other sea surface temperature product what relies on the MODIS data stream.
We apologize for any inconvenience this may cause. |

02 February 2009:
PO.DAAC Alert: PLANNED 2-DAY SYSTEM OUTAGE |
|
PLANNED SYSTEM OUTAGE: PO.DAAC's website: http://podaac.jpl.nasa.gov and all PO.DAAC data tools and services (including POET, FTP, OPeNDAP/DODS, and Aspera sites) will be unavailable for approximately 2 days on February 7th - 8th, starting at 8:00pm PST on Friday, February 6th due to scheduled facility maintenance activities. Services should be restored sometime after 10am on Monday, February 9th.
Please note, the only exception is that Jason OSDR NRT data, if produced (see announcement regarding Jason-1 orbit maneuver), will continue to be available at: ftp://podaac.jpl.nasa.gov/sea_surface_height/jason/osdr/. |

PO.DAAC Jason-1 Manuever Announcement |
|
After more than 7 years of service on the nominal ground track, the Jason-1 satellite will be moved to a new interleaved orbit with OSTM/Jason-2 at the end of repeat cycle 259. The OSTM/Jason-2 satellite will continue the long term climate data record on the primary TOPEX/Poseidon--Jason-1--OSTM/Jason-2 ground track. Interleaving Jason-1 with OSTM/Jason-2 orbits will provide significant advantages for operational applications.
Beginning on 26 January 2009, several Jason-1 maneuvers will be performed to reach the new interleaved orbit by 9 February 2009. Due to altimeter limitations, no Jason-1 science data will acquired during this maneuver period and repeat cycles 260 and 261 will be lost.
Repeat cycle 262 will be the first Jason-1 cycle on the new interleaved ground track. The new orbit will be phased 162-degrees ahead of OSTM/Jason-2 with a time lag of approximately five days. This is the same interleaved orbit that was used by TOPEX/Poseidon from 2002-2005. The pass numbering within the cycle will also change to the pass numbering system that TOPEX/Poseidon used during its interleaved orbit phase.
Jason-1 OSDR production will resume shortly after the maneuvers are completed. Jason-1 IGDR and GDR products will become available after February 9, once the Project is confident of the accuracy of the new orbit calculations and tuning of POE models.

International GHRSST Data Users Symposium
28-29 May 2009, Santa Rosa, CA
The Group for High-Resolution Sea Surface Temperature (GHRSST) project provides a new generation of uniformly processed satellite SST data and global high-resolution (<10km) SST products to the operational oceanographic, meteorological, climate and general scientific community. More information on the project is at
http://www.ghrsst-pp.org/. The symposium will update SST data users on satellite data sets and the current status of blended products. We are requesting presentations on the latest research and/or applications using GHRSST data. Topics may include, but are not limited to: oceanographic research, air-sea interactions, coral reefs, ocean modeling and forecasting, maritime pollution monitoring, coastal environmental protecting and management, fisheries, marine park management, sea ice, ocean circulation, and data assimilation systems. The two day symposium aims to assemble a diverse group of scientists to discuss recent advances in the knowledge of processes related to sea surface temperature and foster enhanced collaboration between GHRSST data users and research groups.
The GHRSST Data Users Symposium will be held at the Vineyard Creek Hyatt in Santa Rosa, CA, USA, from 28 to 29 May 2009, at the invitation of Remote Sensing Systems and NASA's Jet Propulsion Laboratory Physical Oceanography Distributed Active Archive Center (PO.DAAC). A detailed agenda will be established and circulated later, however we suggest that an early reservation is made for hotels, as Santa Rosa is a popular travel destination. Deadline for registration is 31 January 2009. More
