News from Remote Sensing Systems
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
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.
To provide better data services, RSS will require all data users to register.
All RSS data users will be required to register by December 12, 2016.
RSS has completed an initial investigation and corrected a problem affecting SSMIS F17.
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.
This change to the RSS air temperature TMT product represents a major upgrade with 4 important changes.
RSS MSU/AMSU temperature data record has been in the news a lot lately and to address the many questions we receive, we've posted this information.
The plots and discussion in the Climate part of the RSS website has been updated to reflect recent AMSU measurements.

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.
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.
A first-light animation of SMAP ocean salinity, showing 7-day averages centered on each day from the beginning of April to the beginning of July 2015, has been released by RSS.
In 2013, Thomas Meissner and Frank J.
I (Carl Mears) am currently involved in an online dialogue/debate with Steven Sherwood and John Christy. The dialogue is hosted at Climate Dialogue.

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
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.
