Quantification of rotavirus diarrheal risk due to hydroclimatic extremes over south Asia: Prospects of satellite‐based observations in detecting outbreaks

Rotavirus is the most common cause of diarrheal disease among children under 5. Especially in South Asia, rotavirus remains the leading cause of mortality in children due to diarrhea. As climatic extremes and safe water availability significantly influence diarrheal disease impacts in human populations, hydroclimatic information can be a potential …

Dynamics of a river system– the case of the Kosi river in north Bihar

The paper presents an account of the Kusaha breach of the Kosi river which has been widely perceived as a flood event in the media and scientific circles. It is true that a large area was inundated after this event but it is important to appreciate that this inundation was …

Avulsion threshold and planform dynamics of the Kosi River in north Bihar (India) and Nepal: A GIS framework

Models for river avulsions have identified the ratio between down-valley and cross-valley slopes of channels as the triggering factors for the sudden channel shift but have remained untested in the field. The August 2008 avulsion of the Kosi River at Kusaha, 12 km upstream of the Kosi barrage in Nepal, …

Groundwater depletion in the West Liaohe River Basin, China and its implications revealed by GRACE and in situ measurements

The West Liaohe River Basin (WLRB) is one of the most sensitive areas to climate change in China and an important grain production base in the Inner Mongolia Autonomous Region of China. Groundwater depletion in this region is becoming a critical issue. Here, we used the Gravity Recovery and Climate …

Maritime NOx emissions over Chinese seas derived from satellite observations

By applying an inversion algorithm to NOx satellite observations from Ozone Monitoring Instrument, monthly NOx emissions for a 10 year period (2007 to 2016) over Chinese seas are presented for the first time. No effective regulations on NOx emissions have been implemented for ships in China, which is reflected in …

China to build platform for supervising environmental 'red lines'

BEIJING — China is planning to complete the construction of a platform for supervising the "red lines" for the protecting important natural areas by 2020, according to the Ministry of Environmental Protection (MEP). With total investment of 286 million yuan (about $45 million), the construction plan has been approved by …

Climate-change–driven accelerated sea-level rise detected in the altimeter era

Satellite altimetry has shown that global mean sea level has been rising at a rate of ∼3 ± 0.4 mm/y since 1993. Using the altimeter record coupled with careful consideration of interannual and decadal variability as well as potential instrument errors, we show that this rate is accelerating at 0.084 …

Using satellite imagery to assess impacts of soil and water conservation measures : evidence from Ethiopia's Tana-Beles Watershed

Although efforts at soil and water conservation are routinely viewed as instrumental in reducing vulnerability to climate change, their impact has rarely been quantified. Combining data on the timing and intensity of soil and water conservation interventions in select Ethiopian watersheds from 2009 to 2016 with a pixel-level panel of …

Remote sensing of motor vehicle exhaust emissions

This report provides a comprehensive overview of vehicle remote sensing, an emissions measurement technique which has been used for more than 25 years to evaluate emissions from passing motor vehicles in real-world driving. Review technical details of the vehicle remote sensing test method, describe the multiple types of emissions analyses …

A country level assessment of area under agroforestry and its carbon sequestration potential

National Innovations on Climate Resilient Agriculture (NICRA) is a network project of Indian Council of Agricultural Research, which was launched in February, 2011. The project aims to enhance resilience of Indian agriculture to climate change and climate vulnerability through strategic research and technology demonstration. The research on adaptation and mitigation …

Global models underestimate large decadal declining and rising water storage trends relative to GRACE satellite data

We increasingly rely on global models to project impacts of humans and climate on water resources. How reliable are these models? While past model intercomparison projects focused on water fluxes, we provide here the first comprehensive comparison of land total water storage trends from seven global models to trends from …

Estimation of the PM2.5 pollution levels in Beijing based on nighttime light data from the defense meteorological satellite program-operational linescan system

Nighttime light data record the artificial light on the Earth’s surface and can be used to estimate the degree of pollution associated with particulate matter with an aerodynamic diameter of less than 2.5 μm (PM2.5) in the ground-level atmosphere. This study proposes a simple method for monitoring PM2.5 concentrations at …

Ocean bottom deformation due to present-day mass redistribution and its impact on sea level observations

Present-day mass redistribution increases the total ocean mass and, on average, causes the ocean bottom to subside elastically. Therefore, barystatic sea level rise is larger than the resulting global mean geocentric sea level rise, observed by satellite altimetry and GPS-corrected tide gauges. We use realistic estimates of mass redistribution from …

GIS-based bivariate statistical techniques for groundwater potential analysis (an example of Iran)

Groundwater potential analysis prepares better comprehension of hydrological settings of different regions. This study shows the potency of two GIS-based data driven bivariate techniques namely statistical index (SI) and Dempster–Shafer theory (DST) to analyze groundwater potential in Broujerd region of Iran. The research was done using 11 groundwater conditioning factors …

Decline in Antarctic ozone depletion and lower stratospheric chlorine determined from aura microwave limb sounder observations

Attribution of Antarctic ozone recovery to the Montreal protocol requires evidence that (1) Antarctic chlorine levels are declining and (2) there is a reduction in ozone depletion in response to a chlorine decline. We use Aura Microwave Limb Sounder measurements of O3, HCl, and N2O to demonstrate that inorganic chlorine …

Recent changes in populations of critically endangered Gyps vultures in India

Populations of the White-rumped Vulture Gyps bengalensis, Indian Vulture G. indicus and Slender-billed Vulture G. tenuirostris declined rapidly during the mid-1990s all over their ranges in the Indian subcontinent because of poisoning due to veterinary use of the non-steroidal anti-inflammatory drug diclofenac. This paper reports results from the latest in …

Reassessment of water availability in India using space inputs

Considering the importance of fresh reassessment of water resources availability in the country, Ministry of Water Resources, River Development and Ganga Rejuvenation (MoWR, RD & GR), Government of India had approved study for “Reassessment of Water Availability of River Basins in India using Space Inputs” for assessing the average annual …

Generation and validation of the interferometric SAR DEMs from TanDEM-X data for Gangotri and Hamtah glaciers of Indian Himalayas

TanDEM-X SAR mission was launched in June, 2010 with an aim to generate high resolution global DEMs of HRTI-3 specification. Considering this, it is very important to evaluate the accuracy of the DEM generated using TanDEM-X InSAR data over the rugged terrains of Indian Himalayas. This paper presents the results …

Regional representation of glaciers in Chandra Basin region, western Himalaya, India

Hamtah and Chhota Shigri are two nearby, well monitored glaciers of western Himalaya, lying in the same climatic zone and driven by the same climatic conditions.
