Abstract
Abstract. The lack of long-term and high-quality solar radiation data has
been an obstacle for scientific and industrial fields. In this study, a
dense station-based, long-term and high-accuracy dataset of daily surface
solar radiation was developed using two surface radiation models. One is the
model developed by Yang et al. (2006) for global radiation estimation, and
the other is the model developed by Tang et al. (2018) for direct radiation
estimation. The main inputs for the development of the dataset are surface
pressure, air temperature, relative humidity, horizontal visibility and
sunshine duration, which are the routine meteorological variables observed
at the 2743 China Meteorological Administration (CMA) weather stations.
Validation against in situ observations and comparisons with two
satellite-based radiation products shows that our station-based radiation
dataset clearly outperforms the satellite-based radiation products at both
daily and monthly scales. In addition, our dataset is available for more
than 60 years and includes three radiation components of global, direct and
diffuse radiation, which is not possible with satellite products. This
station-based radiation dataset will contribute to the climate change
research and solar energy engineering applications in the future. The
station-based dataset is now available at
