Abstract Resilience is the central concept for understanding how an ecosystem responds to a strong perturbation, and related other concepts used analyze system properties in face of change such as resistance, recovery, sustainability, vulnerability, stability, adaptive capacity, regime shift, tipping point. It extremely challenging formulate resilience thinking into practice. The current state-...

In recent years extensive studies on the Earth’s climate system have been carried out by means of advanced complex network statistics. The great majority of recent studies, however, have been focusing on investigating interaction structures within single climatological fields directly on or parallel to the Earth’s surface. It is well-known, however, that many processes observed in the Earth sys...

A near-real time GMES-relevant monitoring system for semi-operational retrieval of snow covered area for hydrological and climatological applications has been developed in the Envisnow EC EESD FP 5 project. The system, using ENVISAT ASAR wide swath data from ESA AOE 785 and from the Kongsberg satellite station, geocodes and classifies Envisat ASAR data automatically, and produces SCA maps with ...

Appropriate spatial scales of hydrological variables were determined using an existing methodology based on a balance in uncertainties from model inputs and parameters extended with a criterion based on a maximum model output uncertainty. The original methodology uses different relationships between scales and variable statistics. It is extended with two different uncertainty propagation method...

A technique is proposed for smoothing a broken line fit, with known break points, to observational data. It will be referred to as “broken line smoothing”. The smoothness term is defined by means of the angles formed by the consecutive segments of the broken line, and is given an adjustable weight. The roughness of the resulting broken line can then be controlled by appropriately tuning the wei...

Abstract—An operational nonlinear Physical Inversion (PIn) algorithm for precipitable and cloud liquid water estimate is described. It is suited for a generic conical scanning satellite microwave radiometer acquisitions over sea, in non-raining conditions. The algorithm does not need any calibration phase, and is independent from the availability of in-situ data, being consistent in different g...

Thirteen equations based on the mass-transfer method for determining free water evaporation were expressed in seven generalized equations. These seven equations were then compared with pan evaporation at four climatological stations in north-western Ontario, Canada. The comparisons were based on monthly evaporation. Equations were compared by calibrating them on the entire data sets as well as ...
