A Prototype Drought Monitoring System Integrating Climate and Satellite Data
Droughts are natural hazards with varying patterns in space, time, and intensity. Their dynamic character challenges our ability in planning, predicting, monitoring, and providing relief to affected areas. Because of the spatial and temporal variability and multiple impacts of droughts, we need to improve the tools and data available for mapping and monitoring this phenomenon on all scales. A t...
متن کاملClimate change adaptation for the US National Wildlife Refuge System.
Since its establishment in 1903, the National Wildlife Refuge System (NWRS) has grown to 635 units and 37 Wetland Management Districts in the United States and its territories. These units provide the seasonal habitats necessary for migratory waterfowl and other species to complete their annual life cycles. Habitat conversion and fragmentation, invasive species, pollution, and competition for w...
متن کاملCalibration of Optical Satellite Sensors
Satellite cameras are calibrated before launch in detail and in general, but it cannot be guaranteed that the geometry is not changing during launch and caused by thermal influences and drying out effects in the orbit. Modern satellite imaging systems are based on CCD-line sensors. Because of the required high sampling rate, the length of used CCD-lines is limited. For reaching a sufficient swa...
متن کاملUS Climate Change Policy Efforts
for Strategic Environmental Research (Mistra), focuses on future international policies in the area of climate change. Carried out by a consortium of universities, think tanks and non-governmental organisations in Europe, India and the US, the main aim of the programme is directed towards the use of economic incentives and instruments in the implementation of climate policies, and towards the d...
متن کاملRole of Satellite Sensors in Groundwater Exploration
Spatial as well as spectral resolution has a very important role to play in water resource management. It was a challenge to explore the groundwater and rainwater harvesting sites in the Aravalli Quartzite-Granite-Pegmatite Precambrian terrain of Delhi, India. Use of only panchromatic sensor data of IRS-1D satellite with 5.8-meter spatial resolution has the potential to infer lineaments and fau...
