Several recent studies have concluded that climate change causes major changes in the global water cycle. There is increasing evidence that part of the multi-decadal trends observed on the sea surface salinity (SSS) are due to changes in the global water cycle, e.g. the western tropical Pacific has become fresher and the subtropical North Atlantic …
A webinar to learn how Sentinel data can contribute to freshwater monitoring, in particular by observing water-quality indicators such as concentrations of Chlorophyll-a, Total suspended matter (TSM), Coloured dissolved organic matter (CDOM), as well as density of cyanobacteria and water turbidity. Apply from Thursday 13th to Thursday 27th February 2020. The RUS Service is funded …
Water quality and access is essential for socio-economic development and for maintaining healthy ecosystems. Properly managed water resources are a critical component of growth, poverty reduction and equity. The Thematic Exploitation Platform (TEP) for Hydrology is a heterogeneous community of scientific users, river basin organisations and service providers. The aim of this community is to exchange data, …
The Arctic is a complex region encompassing different physical and biogeochemical processes and interactions among several components of the Earth system (e.g., sea ice, ocean, glaciers, ice caps, the Greenland Ice Sheet, snow, lakes and river ice, permafrost, vegetation, complex interactions with the atmosphere, people, etc.). Changes in the Arctic have a strong impact on …
Follow the links and find out about the importance of studying the whole water cycle and how this has been tackled in the Mediterranean within a recently published paper presented at the Living Planet Symposium.
The STREAM Project (SaTellite based Runoff Evaluation And Mapping), led by CNR-IRPI with the participation of the Institute of Geodesy (GIS) at University of Stuttgart, aimed at developing innovative methods able to maximize the recovery of information on runoff contained in current satellite observations of climatic and environmental variables (i.e., precipitation, soil moisture, terrestrial water …
The RIDESAT Project (RIver flow monitoring and Discharge Estimation by integrating multiple SATellite data) aims at developing a new methodology for the joint exploitation of three sensors (altimeter, optical and thermal) for river flow monitoring and discharge estimation. Even if with a number of limitations, satellite radar altimetry over surface inland water has demonstrated its …
A good aircraft heating was necessary to secure proper functioning of the on-board instrumentation during the airborne campaign that took place last November in the Arctic, flying between Ottawa and Iqaluit. The campaign exploited several radars and lidars to measure cloud particles and precipitation by looking at signals bouncing off ice crystals and water droplets …
The gravity gradients of the highly successful ESA Earth Explorer mission GOCE (Gravity field and steady-state ocean circulation explorer), which have been reprocessed by applying enhanced calibration strategies in the frame of the ESA project GOCE High-level Processing Facility (HPF), have reached a very high quality level, especially in the long-wavelength spectral range where the …
The possibility to operationally monitor the Earth’s land cover (changes) at high temporal resolution is nowadays given by EO multispectral dense time series available at global level, in particular Sentinel-2 and Landsat 8 data. Nonetheless, keeping thematic maps regularly updated is a complex and time consuming task. Large efforts have been devoted to date in …
