CIRA’s Satellite Loop Interactive Data Explorer in Realtime (SLIDER) website (https://rammb-slider.cira.colostate.edu) has long been used by forecasters around the world to view geostationary and polar-orbiting satellite data from around the globe. Now, a new feature has been added to combine the best of both over the Contiguous United States (CONUS): the JPSS CONUS Sector. This new sector, available from the JPSS satellite menu, combines low latency VIIRS imagery from CIMSS Direct Broadcast with blended ABI imagery – from both GOES-East and GOES-West – remapped to a common domain. Examples are shown in the figures below. Thanks to SLIDER’s overlay capabilities, it is now possible to overlay VIIRS imagery on top of ABI (or vice versa) to directly compare the two imagers. The ABI imagery products blend Full Disk GOES-East and GOES-West across the Utah/Colorado border (the longitude where the spatial resolutions of the two ABIs are approximately equal), and also uses the ABI terrain-correction developed by Chris Schmidt at CIMSS for improved mapping. This improves the spatial matching between ABI and VIIRS. (VIIRS imagery has always been terrain-corrected on SLIDER.) Zoom levels are based on the native resolution of VIIRS (375 m resolution for the I-bands). At the present time, the JPSS CONUS sector offers all 22 VIIRS bands (from all three VIIRS instruments), all 16 ABI bands, and a variety of multispectral imagery products and RGB composites from both VIIRS and ABI.

We strive to add the full suite of products offered by the current GOES-16/18 CONUS sectors on SLIDER on this new JPSS CONUS sector. The new JPSS CONUS sector is now the default view when selecting “JPSS” from the satellite menu, so it may be accessed directly from this link: https://rammb-slider.cira.colostate.edu/?sat=jpss. And, note that the hemispheric composites of VIIRS imagery that Polar SLIDER is known for are still available. They may be accessed by choosing the proper sector from the menu of the JPSS page.
