Joint Polar Satellite System’s Microwave Instrument Fully Assembled
The Advanced Technology Microwave Sounder (ATMS) for the National Oceanic and Atmospheric Administration’s Joint Polar Satellite System-2 spacecraft, scheduled to launch in 2022, has been fully assembled and has begun environmental testing.
Satellite Imagery RGBs: Adding Value, Saving Time
With the advent of the GOES-R Series, forecasters now have an overwhelming amount of information to sift through. The Advanced Baseline Imager (ABI) instrument has 16 channels that image Earth’s weather, oceans and environment as often as every 30 seconds. How can meteorologists quickly discern the information they need to issue timely forecasts and warnings? Scientists are working on new ways to combine information from multiple ABI channels to enhance meteorological features of interest. The result is a variety of red-green-blue or “RGB” composite imagery. The stunning, colorful imagery you see from GOES-16 and GOES-17 isn’t just beautiful to look at, it also provides critical information to forecasters for situational awareness and nowcasting rapidly changing weather.
A Guide to Understanding Satellite Images of Hurricanes
On the morning of September 2, 2019, as a devastating Hurricane Dorian made landfall over three islands in the Bahamas, delivering torrential rain and sustained winds of 185 miles per hour, the VIIRS instruments on the NOAA-20 and NASA-NOAA Suomi-NPP (S-NPP) satellites captured infrared pictures from above. These images, caught at 2:13 am ET and 3:03 am ET respectively, showed a circular eye inside a nearly perfectly symmetrical Category-5 storm. 
Marine Heat Wave Reminiscent of 'the Blob' Lingers off U.S. West Coast
The new marine heat wave off the Pacific Coast is reminiscent of the early stages of the 2014–2016 “blob” that devastated marine life and is believed to have affected the weather. This year’s expanse of unusually warm water stretches roughly from the Gulf of Alaska south to California and west all the way to Hawaii. 
First Federal Broadband Point of Presence in the Arctic Paves the Way for New Research
Utqiaġvik, Alaska, the farthest north point in the U.S., is a critical location for international Arctic research. Its history includes many decades of research by academia, all major U.S. science agencies, and international partners, making it a baseline location for Arctic research in the U.S. However, historically, poor network connectivity has limited the science and operations that can be done in Utqiaġvik.
Dive Into NOAA’s Treasure Trove of Data
“It is a capital mistake to theorize before one has data,” said the great detective Sherlock Holmes in Sir Arthur Conan Doyle’s short story entitled “A Scandal in Bohemia.” We at NOAA couldn’t agree more and are highlighting the amazing things we can learn from data throughout the month of September during a celebration known as NOAA DataFest. After all, NOAA data are freely available to all who want to learn about the world and its many mysteries.    
NOAA Sees the Fifth Hurricane Humberto Through High-powered Lens
This season’s Humberto isn’t the first tropical cyclone in the Atlantic Basin to be given the name. In fact, it’s the fifth Hurricane Humberto to emerge in the Atlantic, but this time, NOAA is watching through the sophisticated Advanced Baseline Imager (ABI) of GOES-16.

The 2004 Atlantic Hurricane Season: A Look Back from Above
In 2004, the Atlantic Basin had one of its most active and destructive hurricane seasons on record. When the season finally ended, it ultimately produced more than $61 billion in damage and caused thousands of deaths across several countries.  Fifteen years later, we’re reviewing the season and highlighting a few of the monsters — from NOAA’s satellites’ perspective.

How Bits and Bytes of Data Become a Forecast
Every day in America, millions of people wake up with the same question on their minds, “What’s the weather today?” The US Department of Commerce found that the majority of Americans check the weather forecast 3.8 times per day, equating to 301 billion forecasts consumed per year! These days, we take accurate forecasts — available multiple days in advance — for granted.
