LANCE AMSR 2 Imagery • GIBS Imagery available for all products o NASA’s Worldview: https: //worldview. earthdata. nasa. gov/ • “Events” tab, is a new capability in Worldview / GIBS to interactively explore current natural events across the globe. https: //earthdata. nasa. gov/new-worldview-eventsfeature-lets-users-explore-images-of-current-naturalhazards-at-the-click-of-a-button On 8/28/2016 two tropical cyclones, Madeleine and Lester, approached the Hawaiian Islands with anticipated tropical cyclone track forecasts bringing each to the south and north of the Big Island. This rare event raised concerns for flash flooding due to observed heavy rainfall amounts and high surf for several of the eastern islands. In the end, both tropical cyclones skirted the Hawaiian Islands, bringing only high waves and rain. This LANCE AMSR 2 NRT daily columnar water vapor retrieval image was derived from measurements taken by the AMSR 2 instrument onboard the GCOM-W 1 satellite. LANCE UWG 9/27/2016 5

LANCE AMSR 2 net. CDF Format • SIPS is working to provide the LANCE NRT AMSR 2 products in net. CDF/CF format. Conversion of the Rain. Ocean, Snow, and Sea. Ice 6 datasets to net. CDF/CF is in progress. • Current HDF-EOS 5 files will be augmented to be net. CDF compatible. • Dataset Interoperability Recommendations for Earth Science are being used: https: //earthdata. nasa. gov/user -resources/standards-and-references • Sample net. CDF/CF files for Snow and Sea. Ice 6 are available at: http: //lance. nsstc. nasa. gov/amsr 2 science/samples/ • We would like feedback about these data files. • Do these net. CDF/CF files work with your software and tools? • Is this the preferred net. CDF approach for LANCE data? LANCE UWG 9/27/2016 7
