JPL SMAP-SSS V4.0 dataset released

February 22, 2018

The JPL SMAP Version 4.0 datasets spans the full mission, with data available from 2 April 2015 to present. Global coverage data products include an 8-day running mean as well as monthly averages. Level 2 swath data are also available as part of the product release. They are available with a latency of 3 days for the L2 dataset, and 8 days and 1 month for the respective L3 products. The spatial resolution of the SMAP sensor, approximately 40 km, allows for improved applications to coastal and regional studies.  The image shows the seasonal average surface salinity for the summer of 2015. Clearly visible is the freshwater plume that is typical for the Gulf of Mexico. Features associated with the Loop Current can also be identified.

Data is available through PO.DAAC Drive at: podaac-tools.jpl.nasa.gov/drive/files/allData/smap

Subsetting and data extraction are available through https://podaac-tools.jpl.nasa.gov/las/UI.vm

JPL SMAP Summer 2015

Modeling marine fish species spatiotemporal distributions utilizing NASA earth system data in a maximum entropy framework (February, 2018)

Fishermen rely on their on-the-water experience to know where and when to find certain species of fish in the Gulf of Maine, and managers use their knowledge of fish and the fishery to design management policies, such as seasonal closures, aimed at ensuring sustainability. Increasingly, climate change is altering historical relationships between the physical environment and our fishery resources, and challenging both fishermen and managers.

Data in Action: Modeling marine fish species spatiotemporal distributions utilizing NASA data

Fishermen rely on their on-the-water experience to know where and when to find certain species of fish in the Gulf of Maine, and managers use their knowledge of fish and the fishery to design management policies, such as seasonal closures, aimed at ensuring sustainability. The ability to understand where fish are likely to be and when they are likely to be there is critical for the sustainable management of the region's valuable fisheries.

Public Release of the NASA/GSFC AQUARIUS RFI Level 3, Version 1.0 Product by the PO.DAAC

2018-01-25

The PO.DAAC is pleased to announce the availability of the level 3, monthly Aquarius Radio Frequency Interference (RFI) V1.0 dataset produced by NASA/GSFC.  The product provides insight into the global distribution of RFI at L-band and serves as a useful adjunct to the Aquarius V5.0 end-of-mission data recently released.  Maps of percentage RFI can give the user an indication of where RFI is more likely to have affected the quality of SSS retrievals over the ocean on monthly time
