A Quality Control Concept for Radar Reflectivity, Polarimetric Parameters, and Doppler Velocity

Over the last few years the use of weather radar data has become a fundamental part of various applications like rain-rate estimation, nowcasting of severe weather events, and assimilation into numerical weather prediction models. The increasing demand for radar data necessitates an automated, flexible, and modular quality control. In this paper a quality control procedure is developed for radar reflectivity factors, polarimetric parameters, and Doppler velocity. It consists of several modules that can be extended, modified, and omitted depending on the user requirement, weather situation, and radar characteristics. Data quality is quantified on a pixel-by-pixel basis and encoded into a quality-index field that can be easily interpreted by a nontrained end user or an automated scheme that generates radar products. The quality-index algorithms detect and quantify the influence of beam broadening, the height of the first radar echo, ground clutter contamination, return from non-weather-related objects, and attenuation of electromagnetic energy by hydrometeors on the quality of the radar measurement. The quality-index field is transferred together with the radar data to the end user who chooses the amount of data and the level of quality used for further processing. The calculation of quality-index fields is based on data measured by the polarimetric C-band Doppler radar (POLDIRAD) located in the Alpine foreland in southern Germany

Creating the conditions for self-fulfilment for aged care residents

In 1991 the United Nations General Assembly adopted the Principles for Older Persons as a framework for international policy responses to population ageing. These principles promote independence, participation, care, self-fulfilment and dignity as legitimate entitlements of all older people. Although these principles, or variations of them, are embedded in standards of best-practice in residential aged care facilities, the literature shows that in reality institutional care can deny older people opportunities to exercise some of these entitlements. More specifically, residential aged care facilities can deprive older people of access and support to pursue opportunities for the full development of their potential, i.e. their entitlement to self-fulfilment. This discussion article explores the influence of institutional care on older people’s ability to exercise their entitlement to self-fulfilment. We identify the characteristics of a ‘good life’ in institutional care, according to aged care residents themselves. The Eden AlternativeTM is presented as a model of aged care that aims to create the conditions for a ‘good life’ and self-fulfilment for aged care residents
