The Cloud That Appears on Top of The Most Dangerous Storms
We meteorologists knew that the new GOES satellites would be revolutionary, and a new paper presented at an AMS conference on severe storms is a good example of just that. It’s about a cloud signature visible on high- resolution imagery that can lead to more lead time on severe weather warnings and fewer false alarms. It’s called an AACP: Above Anvil Cirrus Cloud, and when a forecaster sees one on …

Smoke From Western Wildfires Reaches Europe
Some stunning images from the GOES-16 this afternoon. The western U.S. wildfire smoke is now visible over much of Canada and into the northeastern U.S. It’s also clearly visible all the way across the Atlantic to the coast of Portugal! Look at the imagery below: Another view courtesy of CIRA at Colorado State: Now, look at the smoke across the Atlantic. That land at the right edge of the image …

Seeing the World With New Eyes
I want to share with you the kind of satellite imagery forecasters like me are using on a daily basis now, and show you how incredible it is. Thanks to GOES-R we are seeing things we never saw before, but one type of imagery, in particular, is my new favorite. So much so, that I have a running loop up every day on the monitors in our forecast center. It takes some explaining though, …

Using GOES-16 to Detect and Forecast Cold Temperatures
Just where was the coldest spot in New York state this morning? With weather stations, you could get close, but with the new GOES-16 satellite, you can find the exact spot. Just southeast of Philadelphia NY. The bright green in northern New York is a ground temp. of 234K which is around -39 C. Philadelphia NY, in that area had a low of -39.5C. There are some spots nearby showing -40C (F) …

New GOES-16 Weather Satellite Will Be Turned Off for 14 Days
GOES-16 will become the new GOES-EAST satellite late this year as the old GOES-13 is retired. We knew this move was coming but NOAA has just announced the details of the move. Currently, the new GOES-16 is over the equator south of the central U.S. At this checkout location, it can just barely see the edge of Africa, but it gives very good coverage to the western U.S. Once the …

GOES-16 View of the SAL around Tropical Depression 4.
The image above is from GOES-16 (Ctsy. CIRA) and you can easily see the dry dusty Saharan air to the North and east of Tropical Depression 4. This layer of dusty air is called the SAL for Saharan Air Layer, and it often inhibits tropical cyclones. It’s already impacting TD 4. The new GOES-16 continues to wow we meteorologists. Truly, a new era is underway. Update 12 AM EDT 7 July) …

Looking at Lightning From On High! The GLM Works!
The new GOES-16 weather satellite has something no geostationary weather satellite has ever had before. An instrument that can see lightning. In real time. It’s called the Geostationary Lightning Mapper (GLM for short), and while we have been seeing some real time images from GOES-16 for over a month now, the GLM is still being checked out. Today, NASA and Lockheed released some new video of the GLM in action …

GOES-16 Data Back Online
The GOES-16 non-operational data is back online! It’s amazing too. I have been looking at one-minute data of storms over Kentucky and Tennesee tonight, and it is a real WOW. I grabbed the images below, and this data quickly told me that the storms in Kentucky were maintaining their strength. I suspect it was very valuable to the NWS offices in Tennesee and Kentucky tonight. Many warnings were issued and …

Color Imagery from GOES-16 Today
More images from GOES-16 today. This is a geo-color image at 5-minute intervals. The new satellite has sensors that allow images in almost true color and it sends an image every 5 minutes vs 4 times per hour. Images every 3- seconds are possible as well. This is still non-operational test imagery. See my previous post with the first images from lighting mapper.

Why GOES-16 Is Such A Big Deal
I put this piece together about GOES-16 and it aired today. Hat tip to my excellent editor Kevin Reynolds here at WBOC-TV.
