In a previous post, we explored a data interpolation technique that involved running sections of missing GOES-17 Band 13 data through a shape-preserving piecewise cubic spline method in order to fill the data gaps for brightness temperature (BT). (That method was nicknamed ‘pchip’ interpolation.) In this post, we introduce a more... Read More

The animation above shows ACSPO estimates of Lake Surface Temperature (LST) over Lake Michigan from 3 different VIIRS overpasses: NPP at 0703 and 0844, and NOAA-20 at 0753 UTC (despite the AWIPS label!) early on 18 July 2022; VIIRS data were downloaded at the CIMSS Direct Broadcast antennae, and ACSPO...

GOES-18 images shown in this blog post are preliminary and non-operational Overlapping 1-minute Mesoscale Sectors provided 30-second images of GOES-18 “Red” Visible (0.64 µm) data, which showed the circulation of a Mesoscale Convective Vortex (MCV) that moved northward across southern Nevada early in the day on 17 July 2022. Ongoing thunderstorms along the periphery... Read More

Himawari-8 Imagery, above (courtesy JMA, the Japan Meteorological Agency, from this site), shows a cyclonically rotating feature over the western Pacific, approaching the northern Marianas Islands by the end of the animation. Periodic weak convection is forming within the center of the circulation, with more widespread convection developing to its east.... Read More
