“…Whilst satellite retrieval of radiance data over high-latitude regions has been continuing for over two decades, the interpretation of these data is difficult and often ambiguous. The existing cloud climatological data for the Arctic agree upon the fundamental characteristic, namely, in winter the sky is relatively cloud-free but in summer it is generally fairly cloudy (Vowinckel, 1962). Certain features of the Arctic cloud climatology, such as the multiple layering of summertime stratiform clouds, have been analysed in detail by Herman (1977Herman ( , 1980 and Jayaweera (1977Jayaweera ( , 1982.…”

“…Arctic cloud climatologies have been presented by Vowinckel (1962) and Huschke (1969), by Henderson (1967) for the Beaufort Sea and by Voskresenskiy and Chukanin (1959) for low clouds in the eastern Arctic. Most of these analyses drew heavily upon surface station observations although the usefulness of routine weather reconnaissance flights was illustrated in the analyses of Henderson (1967) and Huschke (1969).…”

An analysis of surface observations of cloud characteristics from a selected highlatitude station, Resolute (N. W. T., Canada), is described. The data set has a high temporal resolution (1 h) and is extensive although here we report only on an analysis of 10 years : 1970-1979, inclusive. The pattern of cloudiness variations is more complex than previous studies of Arctic data have suggested. The predominant reported low-level cloud type is stratocumulus, not stratus. The generally overcast summer conditions are found to extend over a considerable period when cloud cover is composed of several layers, often of types other than stratus. This observation of multilayering suggests that middle and high cloud layers may occur more frequently than they can be observed. Clearly a more accurate awareness of hidden cloud is important for improving solutions of the planetary radiation budget. The surface radiation budget is found to be strongly affected by the development of the summertime overcast but also exhibits features caused by the mid-summer break-up of the lower cloud layer. RÉSUMÉ L'analyse des observations sur les caractéristiques des nuages à une station septentrionale choisie, notamment Resolute (T.N.-O., Canada), est décrite. Les données disponibles étaient d'une grande résolution temporelle (1 h) et s'étendaient sur une longue période, notre étude s'est limitée cependant à la décennie s'étendant de 1970 à 1979 inclusivement. Le schéma de la variation de la nébulosité est bien plus complexe que ne le suggéraient les études antérieures des données sur l'arctique. Le nuage bas prédominant est du type stratocumulus et non stratus. On trouve que les conditions généralement nébuleuses en été incluaient une période considérable au cours de laquelle la couverture nuageuse était formée de plusieurs couches qui étaient souvent d'un type autre que le stratus. Cette observation sur les couches multiples suggère que les couches des nuages moyens et hauts sont présents plus fréquem-ment qu'on ne pourrait l'observer. Il est évident qu'une meilleure connaissance des nuages jusqu'à lors non connus est importante dans l'amélioration des solutions du bilan radiatif planétaire. On a trouvé que le bilan radiatif en surface était considérablement affecté par la présence d'une couverture nuageuse totale en été mais présentait aussi certaines caractéristi-ques qui résultaient de la dispersion au cours de la mi-été de la couche nuageuse basse.

“…This numerator is essentially the basis of the Angstrom-Savinov parameterization of observed insolation in terms of fractional cloudcover (Sivkov, 1971). The denominator of this equation represents the enhancement of intensity due to multiple reflection between cloudbase and the snowcover (see Liljequist, 1956, Vowinckel andOrvig, 1962).…”

“…It was found that such accurate insolation models could typically be categorized into three groups: exponential models [5][6][7][8][9][10], atmospheric transmission models [11][12][13] and time series models [14][15][16]. It was assessed that transmission models and time series models were generally not applicable to rural Australia due to their reliance on unavailable climate data such as cloud density in the case of transmission models, or daily insolation data for a large period of time in the case of time series models.…”

A solar photovoltaic plant model has been developed for the comparison of annual energy output of different plants. The solar plant model has been designed to only require climate data commonly available in rural Australia and includes consideration of nonlinear efficiencies within solar photovoltaic systems. The comparative annual energy output of different photovoltaic technologies was identified and the effects of nonlinear efficiencies were examined.
