Application of tomographic ionospheric corrections in WADGPS networks for real-time estimation of integrated water vapour
(Instituto de Navegacion de España, 2021)
Text en actes de congrés
Accés obertIn recent years several authors have developed strategies that estimate the Integrated Water Vapor (IWV), proportional to the Zenith Tropospheric Delay (ZTD), in near real time --i.e. with a delay of one hour or more--. ... -
Arctic sea-ice change tied to its mean state through thermodynamic processes
(Nature Publishing Group, 2018-06-18)
Article
Accés obertOne of the clearest manifestations of ongoing global climate change is the dramatic retreat and thinning of the Arctic sea-ice cover. While all state-of-the-art climate models consistently reproduce the sign of these ... -
