Data Outage Alert for G1SST

2020-01-29

The PO.DAAC is issuing a data outage alert on the GHRSST Level 4 G1SST Global Foundation Sea Surface Temperature Analysis (https://doi.org/10.5067/GHG1S-4FP01) dataset. From 9 December 2019 to present, the G1SST dataset has produced poor quality SST results. This matter is currently being investigated, but due to current lack of support (funding and resources), we do not anticipate a quick resolution to the situation.

QuikSCAT Arctic Sea Ice Age Classification v1.0 (2002-2009)

Animation of the QuikSCAT scatterometer-derived Arctic sea ice classification v1.0 from 20 June 2002 through 23 November 2009. The dataset provides nominal 4.45 km (pixel resolution at reference latitude 70 N) gridded fields that classify First-Year (FY) and Multi-Year (MY) sea ice using SeaWinds on QuikSCAT scatterometer observations on a daily basis. First-Year sea ice is defined as ice that has formed only during that specific year. Multi-Year sea ice is defined as the winter-time ice that survives the summer melt season.

MEaSUREs Pre-SWOT Hydrology Version 2 Datasets Release

2020-01-08

The PO.DAAC is pleased to announce the public release of the MEaSUREs Pre-SWOT Hydrology River Heights, Lake and Reservoir Heights, Area and Storage Version 2 datasets. More information regarding the data is available from PO.DAAC’s mission page. Several enhancements over the previous release are implemented, including daily river heights and improved quality for long term trend analysis.

MEaSUREs Pre-SWOT Hydrology Datasets Release

January 8, 2020

The MEaSUREs Pre-Surface Water and Ocean Topography (SWOT) Hydrology datasets provide time series of river and lake/reservoir heights, lake/reservoir storage, and grids of lake/reservoir surface area. These 5 datasets are derived from ERS-1 & 2, TOPEX/Poseidon, Jason-1, 2 & 3 and MODIS on Aqua and Terra measurements, and are provided as time series for virtual gauges or grids of surface area extent. The intent is to provide satellite data for hydrological measurements that are typically measured from in situ gauges. These data are available every 10 days from October 1992 to November 2018, with the exception of the daily river height dataset.

The MEaSUREs Pre-SWOT Hydrology datasets are described and discoverable via the PO.DAAC data portal. More information regarding the data is available from PO.DAAC's mission page.
