Climate data from air, land, sea and ice in 2013 reflect trends of a warming planet

17 July 2014

In 2013, the vast majority of worldwide climate indicators-greenhouse gases, sea levels, global temperatures, etc.-continued to reflect trends of a warmer planet, according to the indicators assessed in the State of the Climate in 2013 report, released online on 17 July 2014 by the American Meteorological Society.

Architecting an Earth observation strategy for disaster risk management

15 July 2014

Satellites provide a unique perspective for monitoring natural hazards, providing both global and regional information to support analysis and forecasts as well as decision-making activities of emergency management personnel. Geosynchronous sensors can provide continuous regional information on a continental scale in near real time, as frequently seen in weather monitoring by National Oceanic and Atmospheric Administration (NOAA) operational satellites.

Lasers over New Zealand - Atmospheric researchers examine gravity waves

11 July 2014

Atmospheric gravity waves influence the weather and long-term, climate-related atmospheric processes. For a number of nights between 29 June and 23 July 2014, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Falcon research aircraft will be flying over the New Zealand Alps (Southern Alps) to investigate how these waves propagate from Earth's surface up to an altitude of around 100 kilometres using modern laser metrology and other instruments. The results will help to improve climate and weather prediction models.

Observing polar bears from space

09 July 2014

Monitoring wildlife in the Arctic is difficult. Study areas are cold, barren and often inaccessible. For decades scientists have struggled to study animals, like polar bears, which live in these remote areas. Now researchers at the U.S. Geological Survey have begun testing a new, yet counterintuitive solution - rather then get close to the animals, monitor them from afar.

Taking NASA-USGS' Landsat 8 to the beach

02 July 2014

Some things go swimmingly with a summer trip to the beach - sunscreen, mystery novels, cold beverages and sandcastles. Other things - like aquatic algae - are best avoided. The Landsat 8 satellite is helping researchers spot these organisms from space, gathering information that could direct beachgoers away from contaminated bays and beaches.

A new view: NASA/NOAA water vapour animations over oceans

25 June 2014

Knowing where water vapour is in the atmosphere is one of many factors forecasters use to identify weather features. The NASA/NOAA GOES Project has now created two new types of animations based on satellite data that indicate where water vapour is moving over the Atlantic and Eastern Pacific oceans.

Measuring the irreversible retreat of the West Antarctic Ice Sheet

25 June 2014

Glacial retreat on the West Antarctic Ice Sheet has been a matter of scientific interest for decades and holds serious implications for sea level rise, but difficulties involved in conducting research in this inaccessible location limited early investigation. As remote sensing improved, so too did the capacity to observe glacial patterns on the Antarctic continent.

NASA sees Hurricane Cristina making a reverse in strength

13 June 2014

Hurricane Cristina intensified rapidly on 12 June and infrared satellite data showed cloud top temperatures became extremely cold as thunderstorms towered to the top of the troposphere. One day later, Cristina was weakening quickly and infrared data showed cloud top temperatures were warming as the cloud tops dropped.

For forests, an earlier spring than ever

05 June 2014

Every spring, as the weather warms, trees in forests up and down the east coast explode in a bright green display of life as leaves fill their branches, and every fall, those same leaves provide one of nature's great colour displays of vivid yellow, orange and red.

Earth's magnetic field is important for climate change at high altitudes

23 May 2014

New research has provided scientists with greater insight into the climatic changes happening in the upper atmosphere. Scientists found that changes in the Earth's magnetic field are more relevant for climatic changes in the upper atmosphere (about 100-500 km above the surface) than previously thought.
