SMAP winds for Super-Typhoon Noru
Here we present satellite observations of the intense winds observed during super-typhoon Noru in July-August 2017. These analyses provide additional confirmation that the SMAP radiometer is indeed capable of providing reliable measurements at hurricane-force wind speeds. SMAP data capture the evolution of the intensity, the rapid intensification, and the storm size. At hurricane-force wind speeds, L-band radiometers like SMAP have a unique capability of providing critical information to forecasters about intense Tropical Cyclones, especially in remote location
Historical Comparison of TLT Trends
There have been several recent reports in the media and on social media comparing long-term trends in the lower troposphere from different datasets. The problem is that many of the trends reported were for different periods (i.e 1979-1995 vs. 1979-2016), so we would expect them to be different.

Hurricane Matthew winds from space: A first look
RSS Revives F17 - 37V Anomaly Corrected. Data from March 1, 2016 onward re-released.
RSS has completed an initial investigation and corrected a problem affecting SSMIS F17.
Extreme Winds during Cyclone Winston: A View from Space
We examine space-based extreme winds from tropical cyclone Winston. The SMAP microwave sensor performs well and provides reliable winds in remote regions where other obervations are not available.

Two Rare January Tropical Storms as seen by RSS Data
The tropics have been more active than normal through the early part of 2016. Hurricane Alex, in the North Atlantic Ocean was the first Atlantic hurricane to form in January since 1938.
An Airborne Lake Tahoe?
The amount of extra water vapor sitting in the tropical Pacific atmosphere would, if condensed, fill Lake Tahoe with more to spare! The water vapor anomaly of September 2015 is the largest in satellite history.

2010 Atmospheric Temperature Summary
In the RSS dataset, 2010 was the second warmest year on record in the lower troposphere (TLT), the middle troposphere (TMT), and near the tropopause (TTS). This can be seen in the plot below, which shows the average global temperature anomalies for each of MSU/AMSU channel. The anomalies are so
SST Reveals Pacific Equatorial Current During 1998 La Niña
The plot below shows images of TMI SST in the Equatorial Pacific. South America is apparent in grey on the right hand side of all images and black indicates missing data. The images begin on June 1, 1998 and continue, every 10 days, until August 30, 1998.
