The stratosphere ozone layer is slowly recovering and the recovery will be complete in most parts of the atmosphere in the coming decades, according to the latest bulletin by the World Meteorological Organization (WMO). The bulletin with the updated status of the ozone layer by WMO-Global Atmosphere Watch bulletin returned …
This review presents tropospheric ozone (O3), an air pollutant affecting agriculture by reducing crop yield and deteriorating quality of produce. O3 enters leaves through stomata and diffuses within the apoplast, producing many oxidizing compounds and affecting various physiological and biochemical processes, crop growth and yield. O3 affects above and below …
Before the launch of the Jawaharlal Nehru National Solar Mission (JNNSM) in 2010, not much attention was paid to solar radiation assessment in India. The country had 45 meteorological stations managed by the Indian Meteorological Department to operate as weather observatories, which were not equipped to collect data on direct …
The “Development of Solar Cities” programme by the Ministry of New and Renewable Energy (MNRE), Government of India, is an immense opportunity for contributing towards a sustainable India in the coming years. This programme is a crucial step towards supporting Indian cities for the development of renewable energy and energy …
Solar Radiation Management Governance Initiative (SRMGI) has brought together diverse opinions and expertise from multidisciplinary fields, environmental and development NGOs, industry and civil society organizations from around the globe on the topic of solar radiation management governance. The report, Solar radiation management: the governance of research, summarizes the opinions gathered …
More than twenty years ago, a biological regulation of climate was proposed whereby emissions of dimethyl sulphide from oceanic phytoplankton resulted in the formation of aerosol particles that acted as cloud condensation nuclei in the marine boundary layer. In this hypothesis—referred to as CLAW—the increase in cloud condensation nuclei led …
Solar power is attractive because it is abundant and offers a solution to fossil fuel emissions and global climate change. Earth receives solar energy at the rate of approximately 1,20,000 terawatt. This enormously exceeds both the current annual global energy consumption rate of about 15 TW, and any conceivable requirement …
This document contains the presentation by Sagnik Dey, Centre for Atmospheric Sciences, Indian Institute of Technology Delhi on “Aerosol-Cloud-Climate Interaction: A Case Study from the Indian Ocean” during Second National Research Conference on Climate Change, organized by the Centre for Science and Environment, IIT Delhi and IIT Madras on November …
This document contains the presentation by S. Das et al, Department of Chemical Engineering, Indian Institute of Technology Bombay, Mumbai and University of Iowa, Iowa City, USA on “Data assimilation using optimal interpolation: Correcting chemical transport model predictions with satellite observations” during Second National Research Conference on Climate Change, organized …
Establishing a direct link between climate change and fluctuations in animal populations through long-term monitoring is difficult given the paucity of baseline data. We hypothesized that social wasps are sensitive to climatic variations, and thus studied the impact of ENSO events on social wasp populations in French Guiana. We noted …
Taking the public-private partnerships funding model to the next level, Maharashtra government has decided to set up a network of 2,025 automatic weather stations in the State with the help of private companies. The State government will soon invite expressions of interest for setting up the Rs 122-crore project. Each …
On-board satellite Megha-Tropiques to decode climate phenomena Science meets faith: ISRO chief K Radhakrishnan comes out of the Lord Venkateshwara temple in Tirupati after offering prayers for the successful launch of PSLV-C18, on Tuesday. — PTI Southwest monsoon may soon shed some of its mystery as Indo-French satellite Megha-Tropiques will …
Scientists have demonstrated a clear link between the 11-year sun cycle and winter weather over the northern hemisphere for the first time. They found that low solar activity can contribute to cold winters in the UK, northern Europe and parts of America. But high activity from the sun has the …
CHENNAI, 10 OCT: The Indian Space Research Organisation (ISRO) is getting ready for the launch of PSLV-C18 scheduled at 11 a.m. on 12 October from the Satish Dhawan Space Centre at Sriharikota. The launch will be the twentieth flight of India's more successful Polar Satellite launch vehicle (PSLV). The 50-hour …
Singapore: A cyclical drop in the sun’s radiation can trigger unusually cold winters in parts of North America and Europe, scientists say, a finding that could improve long-range forecasts and help countries prepare for blizzards. Scientists have known for a long time that the sun has an 11-year cycle during …
A huge hole that appeared in the Earth's protective ozone layer above the Arctic in 2011 was the largest recorded in the Northern Hemisphere, triggering worries the event could occur again and be even worse, scientists said in a report on Monday. The ozone layer high in the stratosphere acts …
Relationship of outgoing long-wave radiation (OLR) with convective available potential energy (CAPE) and temperature at the 100-hPa pressure level is examined using daily radiosonde data for a period 1980–2006 over Delhi (28.3˚N, 77.1˚E) and Kolkata (22.3˚N, 88.2˚E), and during 1989–2005 over Cochin (10˚N, 77˚E) and Trivandrum (8.5˚N, 77.0˚E), India. Correlation …
he stable isotope ratios of atmospheric CO2 (18O/16O and 13C/12C) have been monitored since 1977 to improve our understanding of the global carbon cycle, because biosphere–atmosphere exchange fluxes affect the different atomic masses in a measurable way. Interpreting the 18O/16O variability has proved difficult, however, because oxygen isotopes in CO2 …
According to scientists, evaporated water helps in cooling earth as a whole, not just the local area of evaporation, a study said. A new study by scientists at the Indian Institute of Science, the Carnegie Institution for Science at Stanford University and Lawrence Berkeley National Laboratory have demonstrated that evaporation …
The mystery of Earth's missing heat may have been solved: it could lurk deep in oceans, temporarily masking the climate-warming effects of greenhouse gas emissions, researchers reported on Sunday. Climate scientists have long wondered where this so-called missing heat was going, especially over the last decade, when greenhouse emissions kept …
