ITEMS OF INTEREST
- Iceberg slowly disintegrates in southern Indian Ocean -- A
natural-color image obtained at the end of December from the Advanced Land
Imager (ALI) on NASAs Earth Observing-1 (EO-1) satellite shows the
largest remaining section of the B17-B iceberg that broke from
Antarcticas Ross Ice Shelf nearly ten years ago and drifted around the
Southern Ocean before turning northward in the southern Indian Ocean.
Currently, this large section is southwest of Australia. [NASA
Earth Observatory]
- Earth tides may help in earthquake prediction -- A researcher from
Japan's National Research Institute for Earth Science and Disaster Prevention
claims that some of the giant earthquakes, such as the magnitude 9.0 earthquake
of Sumatra that generated the deadly 2004 tsunami in the Indian Ocean, could be
predicted if one looks at the earth tide signal. These earth tides are
associated with the combined effects of the weight of the ocean and
gravitational pull of the sun and moon [Discovery

CURRENT CLIMATE STATUS
- A cold early winter and the Arctic Oscillation -- An image produced
from data obtained from the MODIS sensor on NASA's Terra satellite displays the
land surface temperature anomaly (difference in actual and long-term average
temperatures) for the month of December 2009. This image reveals that large
areas of North America and Eurasia had strong negative temperature anomalies,
or much below average temperatures. Meteorologists from NOAA's National Weather
Service ascribe the unseasonably cold conditions across much of the continents
in the Northern Hemisphere to an unusually negative phase in the Arctic
Oscillation. [NASA Earth
Observatory] While many areas in the United States and Europe experienced a
cold December, some locations across the Canadian Arctic had above average
temperatures, resulting in what a British journalist called
"upside-down" weather. [BBC
News]
Images obtained late last week from the MODIS sensor onboard NASA's Terra
satellite show the snow cover left in the wake of locally heavy snowfall across
widely separated locales such as Great Britain [NASA
Earth Observatory] and northeastern China [NASA Earth
Observatory]
CURRENT CLIMATE MONITORING
- PARASOL satellite leaving the A-Train track -- Engineers with NASA's
Goddard Space Flight Center have taken one of the satellites in NASA's
five-satellite A-Train (Afternoon Constellation) cluster has left the cluster
and going to another orbit. This Earth observation mission satellite called
PARASOL (for "Polarization and Anisotropy of Reflectances for Atmospheric
Sciences coupled with Observations from a Lidar") makes measurements of
aerosols in the Earth's atmosphere using a polarimetry technique. The main
mission of the A-Train satellite formation is the study of the important
variables related to climate change. [NASA
GSFC]
- December storm in Northeast given a major rating -- Winter weather
experts, Dr. Louis Uccellini, director of NOAA's National Centers for
Environmental Prediction, and his colleague Paul Kocin, have recently rated the
winter storm that dropped heavy snow across the Middle Atlantic and New England
States as a "major" category 3 winter storm on their five tiered
Northeast Snowfall Impact Scale. In rating Northeast snowstorms, they use data
obtained from NOAAs National Climatic Data Center. [NOAA
News]
- CIA data shared with climate scientists -- During the last year, the
Director of the Central Intelligence Agency has permitted images of Arctic sea
ice obtained by reconnaissance satellites to be declassified and shared with
climate scientists. [New
York Times]
- Increased accuracy in tracking snowmelt -- Researchers at NASA's Jet
Propulsion Laboratory have developed a new technique that uses data collected
from NASA's Landsat-7 and Terra satellites to be incorporated into a snowmelt
model that tracks the snowpack and the amount of snowmelt water more easily in
mountainous areas. [Science
Daily]
- An All-Hazards Monitor--This Web portal provides the user
information from NOAA on current environmental events that may pose as hazards
such as tropical weather, fire weather, marine weather, severe weather, drought
and floods. [NOAAWatch]
- Global and US Hazards/Climate Extremes -- A review and analysis of
the global impacts of various weather-related events, including drought, floods
and storms during the current month. [NCDC]
CLIMATE FORCING
- Solar eclipses used to study composition of solar corona -- Solar
physicists and astrophysicists from NASAs Goddard Space Flight Center,
along with their colleagues from other institutions in Hawaii and the Czech
Republic have been using spectral images of the solar corona obtained from
ground-based observations during several total solar eclipses during the last
four years. These researchers have been studying the emissions from several
highly ionized lines attributed to iron atoms in the rarified solar atmosphere,
with a goal of improved understanding of how the solar corona affects the
weather and climate on Earth. [NASA
GSFC]
- Volcano watch from space -- A natural color image made from data
collected by the Advanced Land Imager (ALI) aboard NASAs Earth
Observing-1 (EO-1) satellite nearly two weeks ago shows the plume of volcanic
ash and steam emanating from the Soufriere Hills Volcano on the Caribbean
Island of Montserrat. This volcano has become more active within the last
month. [NASA
Earth Observatory]
- Airborne dust -- A MODIS image obtained late last week from NASA's
Terra satellite shows a thick plume of airborne dust being carried across
western Afghanistan and eastern Iran by winds from the dry lake beds in the
Sistan basin. [NASA
Earth Observatory]
- Rock formations along East Coast could store carbon dioxide --
Scientists at Lamont-Doherty Earth Observatory have been considering the
possibility of using volcanic rock formations under coastal sections of New
England and the Middle Atlantic States, along with sections of South Carolina
and Georgia, as reservoirs that would be used to sequester the carbon dioxide
emissions from power plants and other industrial sources. [EurekAlert!]
CLIMATE IMPACTS ON THE BIOSPHERE
- Melting of Arctic Ocean ice cover could result in increased mixing and
marine life -- Researchers at the University of Washington report that the
rapid loss of the Arctic Ocean's summer ice cover could create internal waves
in the Arctic waters that could dramatically change marine life and may even
accelerate the loss of sea ice. [Discovery
News]
- Higher temperatures could reduce carbon uptake in western forests --
Researchers at the University of Colorado and the United Kingdom's Kings
College London conclude that with warmer climatic conditions that include
longer growing seasons, subalpine forests across the West will absorb less
carbon dioxide. [University
of Colorado News]
- Reduction of water flow rates may help the environment --
Researchers at the University of Georgia claim that reduction in water flow
rates through various ecosystems appear to provide better ecological benefits
than attempting to restore the river flow to the natural water flow rates prior
to human intervention. [EurekAlert!]
- Atlantic puffin population affected by worsening North Sea conditions --
Scientists from the United Kingdom's Centre for Ecology & Hydrology and
the British Antarctic Survey who used geo-positioning devices to monitor the
behavior of Atlantic puffin report that the observed decline the population of
these birds is due in part to increased winter mortality associated with
worsening conditions within the North Sea, as well as a migration that is
farther than previously thought. [Centre
for Ecology & Hydrology]
CLIMATE AND SOCIETY
- Solar-powered irrigation project is beneficial for residents sub-Saharan
Africa -- A new study conducted by researchers at Stanford University has
found that solar-powered water pumps installed in remote villages in the West
African nation of Benin to provide irrigation water appears to significantly
enhance household incomes and nutritional intake of the residents of these
villages. [EurekAlert!]
- Website for human dimensions of climate change -- An interagency
effort within the US federal government that included NOAA, the Bureau of Land
Management and the US Forest Service, has resulted in a website called HD.gov
(for HumanDimensions.gov) that provides users, such as natural resource
managers, with information on the human dimensions on a variety of topics of
interest such as climate change. [HD.gov]
COMPARATIVE PLANETOLOGY
- Using sun glints to signal existence of large water bodies -- Space
scientists from NASA's Goddard Space Flight Center and from several research
universities have been studying "sun glint" flashes from video images
obtained by NASA's Deep Impact spacecraft to test a new method for locating
large bodies of water from space. They hope to use this procedure to detect
large liquid reservoirs on the surfaces of "extrasolar" planets
outside or own solar system. [NASA GSFC]
