Homogenized Sunshine duration data for the Austrian domain
2022<p>The measurement of sunshine duration has experienced a number of changes since the operational observation by the national meteorological service ZAMG in Austria. With the automatization of the stations the Campbell-Stokes sunshine recorders were replaced by Haenni Solar 111 instruments and later partly with Meteoservice SD6.

Solar radiation and the duration of sunshine
Quarterly Journal of the Royal Meteorological Society, 1954AbstractRecords of solar radiation (Q) and of duration of sunshine (n) on a monthly basis have been collected for 32 stations and regression equations relating the data calculated in the form Q = QA (a+bn/N) where QA is the maximum possible radiation in the absence of an atmosphere, and N is the maximum possible duration of bright sunshine. For five of

Sunshine duration study within the Mediterranean area
Theoretical and Applied Climatology, 1991The data information of sunshine duration for two different areas on the northern Mediterranean coast are examined. The data concern the same ten years (1968–77) time period, for both areas.

Regression Analysis of Solar Radiation and Sunshine Duration
Architectural Science Review, 1996Regression techniques have been used to investigate the correlations of monthly-average-daily and monthly-average-hourly global, direct and diffuse radiation with bright sunshine hours for Hong Kong. Measured data during the 15-year period from 1979 to 1993 have been used for this study.

Cloudiness and sunshine duration measurements in the U.A.R.
pure and applied geophysics, 1964Seasonal variations of cloudiness have been studied for the different zones of the United Arab Republic. It was found to be very low and to decrease more towards lower latitudes.

A new perspective on the sunshine duration variability
Theoretical and Applied Climatology, 2019The sunshine duration data is analysed here from a new perspective, different from the traditional ones. The study is focused on pairs of periods of shining sun (called clear periods) followed by periods with the sun covered by clouds (called dark periods).

Sunshine Duration Prediction Using 1D Convolutional Neural Networks
2019 6th International Conference on Instrumentation, Control, and Automation (ICA), 2019The duration of solar radiation is one of the essential factors every day, such as agriculture or renewable energy. Forecasting the period of sunshine in various places like Indonesia is difficult. One method that can process sizable historical data for predictions is Deep Learning.

Stochastic models for sunshine duration and solar irradiation
Renewable Energy, 2002Harmonic analysis of sunshine duration and solar irradiation measured at Sebele, Botswana is carried out. The data used consists of the monthly averages and the Julian-days averages of sunshine duration and solar irradiation sequences. This study involves splitting the time series into deterministic and stochastic components, and determining the ...

Tree‐ring reconstructed sunshine duration over central USA
International Journal of Climatology, 1991AbstractTree‐ring chronologies of baldcypress (Taxodium distichum) and post oak (Quercus stellata) from the central United States of America are directly correlated with precipitation, and inversely with percentage possible sunshine during the growing season (March‐June).

Estimating clear-sky beam irradiation from sunshine duration
Solar Energy, 2001Abstract Monthly-averaged climate and turbidity data from five sites in North America and Europe are employed to evaluate the relationships among monthly-averaged observed beam irradiation ( H b and H bn ), clear-sky beam irradiation ( H bc and H bnc ), sunshine duration (s), and daylength (S ...
