Methane (CH4) uptake by steppe soils is affected by a range of specific factors and is a complex process. Increased stocking rate promotes steppe degradation, with unclear consequences for gas exchanges. To assess the effects of grazing management on CH4 uptake in desert steppes, we investigated soil-atmosphere CH4 exchange during the winter-spring transition period.

Astronauts Being Trained For Mission To Look For Minerals, Get Info On How To Destroy It. Washington: Nasa is reportedly training a team of astronauts for a mission to land on an asteroid by the end of the next decade. The US space agency is training the astronauts to land on an asteroid to explore its surface, search for minerals and even learn the skills they may need to destroy it should one pose a threat to the Earth, ‘The Daily Telegraph’ reported.

Met chief says El Nino may affect showers
The monsoon is likely to hit the southern tip of the country on time in the first week of June, said India’s top weather department official on Thursday, a week before the official forecast, lifting hopes of better farm output for the third successive year and a chance to rein in food inflation.
“It will hit Kerala in the first week of June with an error window of 2-3 days,” said India Meteorological Department director general LS Rathore.

South Asian emissions of fossil fuel SO2 and black carbon increased

Human activities are releasing tiny particles (aerosols) into the atmosphere. These human-made aerosols enhance scattering and absorption of solar radiation. They also produce brighter clouds that are less efficient at releasing precipitation. These in turn lead to large reductions in the amount of solar irradiance reaching Earth's surface, a corresponding increase in solar heating of the atmosphere, changes in the atmospheric temperature structure, suppression of rainfall, and less efficient removal of pollutants.

India’s Cabinet has given its approval to a “National Monsoon Mission,” which will equip the weather department with high-end computers, radars and scientific manpower to generate more detailed and accurate forecasts.

India’s current antiquated methods of forecasting the all-important monsoon rains is getting a re-vamp.

No other weather phenomenon generates as much excitement among policymakers and economists, given that it holds the key to farm output, a sector employing half the country’s workforce.

Washington: Earth-like rocky planets that humans could live on may be more common in the universe than stars, says an international team of planetary scientists which included an Indian-origin researcher. Aditya Chopra at Australian National University and colleagues claim that determining whether these planets are habitable has become the new holy grail of astronomy.

India today successfully launched its first indigenous day-night and all-weather radar imaging satellite RISAT-1. It is slated to boost country's remote-sensing capabilities and facilitate agriculture and disaster management. Till now, India depended on images from a Canadian satellite as existing domestic remote-sensing spacecraft cannot take pictures of the earth during cloud cover. "The satellite can give valuable data like soil moisture, glacier positions and other details," Indian Space Research Organisation (ISRO) Chairman K Radhakrishnan said.

Data on surface ozone concentration compiled for a 10-year period from 1990 to 1999 for Pune and Delhi are analyzed in terms of its frequency distribution, annual trend, diurnal variation and its relation with various meteorological and chemical parameters. It is found that the surface ozone concentration range showing highest frequency of occurrence at Pune is 0–5 ppb during winter and post-monsoon seasons and 15–20 ppb and 5–10 ppb during summer and monsoon seasons, respectively. It is 0–5 ppb at Delhi during all the seasons.

IMD, however, cautions that the monsoon may weaken in August-September due to atmospheric changes in the tropical Pacific
India is expected to have a normal monsoon for the third consecutive year, boosting prospects of good harvests and higher rural incomes.
