when most of the satellite data were collected, as well as more recent deforestation trends. Also at Copenhagen, researchers at the Woods Hole Research center in Massachusetts presented another pantropical biomass assessment,
But in March, a study using the same satellite data added confusion to the issue when it failed to find excessive greening2.
and failed to detect any such greening (see'Amazon drought raises research doubts')2. Some go as far as to say that the satellite data aren't good enough to answer the question at all.
It will certainly give scientists another opportunity to pore over the various ground and satellite data,
It's not clear how the debate over satellite data will play out. As the recent PNAS paper indicates,
The group used satellite data to identify the start, end and length of the growing season for the meadow and steppe vegetation of the Tibetan Plateau between 1982 and 2006,

Special locust squads, guided by satellite data to the breeding grounds, have sprayed more than 90,000 hectares since January.
According to an analysis of satellite data by the nonprofit research institute Imazon in Belã m, deforestation was actually 42%lower this June than last.
If that number holds up in the final analysis using higher resolution satellite data it would still be the second lowest loss on record (see'Clearing the Amazon'.
They also need to learn how best to track desertification using satellite data. Remote sensing can measure surface temperature
Although it is too early to see land-use changes in satellite data, the round tables do seem to be affecting the way many companies do business,
says a Brazilian study that combines satellite data and biomass maps to model the change. The difference is in large part due to a natural lag as carbon stocks slowly decay
The satellite data showed that roughly 150 000 trees in the area had been cut down in the preceding years, across an area of about 10 â°km2.

of satellite data from the University of Maryland and the Smithsonian Environmental Research center in Edgewater Md.
While there is satellite data on temperature and thermal distribution in the Amazon going back to the early 1970s it doesn't provide the resolution necessary to build the detailed models we need Silman said.
and five other UMD geographical science researchers drew on the decades-long UMD experience in the use of satellite data to measure changes in forest and other types of land cover.
The researchers analysed high-resolution global satellite data describing the distribution of tree cover in the period 2000-2005 linking this to global data for terrain (slope) climate human activity and a number of political and socioeconomic factors.
They analyzed maps created using Landsat satellite data to determine where the burn destroyed vegetation and exposed soil--and where to focus emergency restoration efforts.
The first Landfire maps took five years of on-the-ground fieldwork computer modeling and poring over satellite data to complete.
and his team combined that information with in depth use of environmental satellite data using a series of images of vegetation growth and rainfall taken over days and weeks.
We're getting close to the stage where for some organisms we can use satellite data in management he said.
The researchers then were able to scale up the plot and Lidar data with freely available satellite data on topography rainfall and vegetation to model carbon stocks at the national level.
For example if satellite data and climate models forecast a good season for rice before seeds are planted even farmers

The NASA-funded study based on newly improved ground and satellite data sets examines critically the relationship between changes in temperature and vegetation productivity in northern latitudes.
The satellite data were collected by the Tropospheric Emission Spectrometer instrument on NASA's Aura spacecraft. When it comes to reducing ozone levels emission reductions in one part of the world may drive greenhouse warming more than a similar level of emission reductions elsewhere said Bowman lead author of the study published recently in the journal Geophysical Research Letters.
Previous studies using conventional optical satellite data produced contradictory results likely due to the difficulty of correcting the optical data for interference by clouds and other atmospheric conditions.
Satellite data are available only for the last 20 years and show that since 1992 the Pine Island and Thwaites glaciers have experienced significant thinning (melting) flow acceleration
Co-author Dr Gerhard Kuhn from AWI explains It was important to get a better understanding of the rapid retreat that we see in the satellite data.
Comparing satellite data to ground data scientists uncovered the cause. It was as it turns out bugs says Robert Kennedy a remote sensing specialist at Boston University who consulted with U s. Forest Service experts to confirm his observations.
Kennedy says to confirm the satellite data they hiked into areas with recent known budworm outbreaks near Mount Rainier With the decline
