“…As a consequence, the measurement error typically can be 5 % for higher solar zenith angles (see Table 1). The accuracy of global irradiance measurements from a silicon photodiode sensor depends on the systematic influences associated with the solar spectrum, solar zenith angles, and detector temperature that affect the signal-to-noise ratio (e.g., Dirmhirn, 1968;Michalsky et al, 1987Michalsky et al, , 1991King et al, 1998;Myers, 2011;Sengupta et al, 2012). Further, the stability of calibration is expected to change by about 1 % over a year, and thus these sensors need to be re-calibrated once every 2 years.…”

Abstract. As part of the High Definition Clouds and Precipitation for advancing Climate Prediction Observational Prototype Experiment (HOPE), a high-density network of 99 silicon photodiode pyranometers was set up around Jülich (10 km × 12 km area) from April to July 2013 to capture the small-scale variability of cloud-induced radiation fields at the surface. In this paper, we provide the details of this unique setup of the pyranometer network, data processing, quality control, and uncertainty assessment under variable conditions. Some exemplary days with clear, broken cloudy, and overcast skies were explored to assess the spatiotemporal observations from the network along with other collocated radiation and sky imager measurements available during the HOPE period.

“…These boundaries are chosen in such way that real cases of each parameter were evenly distributed. The boundaries in E and A are different from those considered in the Michalsky et al ( 1991) study where a rotating shadowband radiometer was used due to the inherent differences between the two measuring techniques with respect to diffuse irradiante. The rotating shadowband radiometer performs a real time correction for the amount of sky radiance blocked by the shadowband when making diffuse measurement because shadowband measurements are not corrected at this stage.…”

Abstract-Toprovide an accurate solar resource assessment, radiometric stations measuring global, diffuse, and direct irradiance must be widespread. Nevertheless, the high capital costs of thermopile instruments, usually used in pyranometry, represent an important obstacle. Therefore, silicon photovoltaic sensors have emerged as a more accessible alternative than standard thermopile sensors. However, their temperature and spectral responses must be taken into account in order to match silicon cells and thermopile responses. Global and diffuse u-radiance have been measured from early 1990 to the end of 1992 in Almeria, southeastem Spain, by means of thermopile and photovoltaic sensor. Polar axis shadowbands were employed to measure the diffuse irradiance. These IO-minute coincident data sets, covering a complete range of atmospheric conditions, have been used to develop a correction procedure for the silicon detector measurements. Before the correction procedure was applied severe discrepancies were found, especially for the diffuse irradiance measurements performed under clear skies. Results of the correction method applied to an independent data set show a remarkable improvement.After correction, the comparison of silicon cell measurements with those obtained by means of thermopile pyranometers leads to a root mean square deviation of about 4% and 5% over the mean value of global and diffuse horizontal irradiance, respectively.

“…Also, the wellknown uncertainties of silicon photodiode sensors, namely, temperature-dependence of sensor response, cosine response errors, varying spectral atmospheric conditions etc. reported in various studies (Dirmhirn, 1968;Michalsky et al, 1987Michalsky et al, , 1991King and Myers, 1997) are not accounted for in this study.

Abstract. As part of the High Definition Clouds and Precipitation for advancing Climate Prediction Observational Prototype Experiment (HOPE), a high spatial density network of 99 silicon photodiode pyranometers was set up around Jülich (10 km x 12 km area) from April to July 2013, to capture the variability in the radiation field at the surface induced by small-scale cloud inhomogeneity. Each of these autonomously operated pyranometer stations was equipped with weather sensors for simultaneous measurements of ambient air temperature and relative humidity. In this paper, we provide the details of this unique setup of the pyranometer network and the data analysis with initial quality screening procedure we adopted. We also present some exemplary cases consisting of the days with clear, broken cloudy and overcast skies to assess our spatio-temporal observations from the network, and validate their consistency with other collocated radiation measurements available during the HOPE period.
