SMAP winds for Super-Typhoon Noru

By Lucrezia on Aug 10th, 2017

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

By Carl on Jul 6th, 2017

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.

Extreme Winds during Cyclone Winston: A View from Space

By Lucrezia on Mar 15th, 2016

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

By white on Jan 26th, 2016

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?

By Anonymous on Oct 22nd, 2015

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.

Warm Spring in North America

By Carl on Jul 11th, 2012
This March and April, numerous high temperature records were broken in the the Central and Eastern United States.  These warm temperatures extended into the lower troposphere as can easily be seen in maps of lower tropospheric (TLT) temperature Anomalies.

Transition from El Niño to La Niña

By Carl on May 14th, 2011
At the beginning of 2010, the tropical climate system was undergoing a strong El Niño event, characterized by reduced oceanic upwelling in the tropical pacific, leading to warmer than normal SSTs near the equator in the pacific.  This in turn causes warmer than normal temperatures throughout th

2010 Atmospheric Temperature Summary

By Carl on May 14th, 2011

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

By Anonymous on May 6th, 2010

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.
