LAI observation calibration and validation dataset
on Yucheng Station titled Shandong Yucheng Station Observation Node Daily
Average Leaf Area Index Dataset (2020) was developed by Professor Zhou, Xiang’s
team of National Engineering Laboratory for Satellite Remote Sensing
Applications (NELRS) of Aerospace Information Research Institute, Chinese
Academy of Sciences (AIRCAS). It was published in March 2021 at the Digital Journal of Global Change Data
Repository[1]; the data paper matching with the dataset was
published in June 2021 at the Journal of
Global Change Data and Discovery[2]. It is the first dataset
together with full description to be published from the China LAI Observation
Cal-Val Network (“China LAI Cal-Val” for short) , which was initialed in 2018.
The “China LAI
Cal-Val” is the first one of the satellite oriented ground Cal-Val Systems of
China, which is supported by the “National Civil Space Infrastructure
Terrestrial Observation Satellite Common Application Support Platform” (NCSISP)
project and financed by the National Development and Reform Commission of P. R.
China. The purpose of this system is to conduct a specific ecosystem types,
long-term LAI calibration and validation network in China. It is consisted of
14 stations covering most geographical regions and ecosystem classes of China.
They are Guyuan, Nanjing, Daxinganling, Jingyuetan, Jiangshanjiao, Xitianshan,
Haibei, Yucheng, Luancheng, Hefei, Qiyang, Dongting Lake, Qianyanzhou and
Guangzhou stations. The Yucheng Station, one of the “China LAI Cal-Val” network
stations is located at 116°34'17.08"E, 36°49'44.64"N, its
function is the LAI Cal-Val for the wheat-corn double cropping rotated farmland
system in the warm temperate zone of China.
The LAI refers to
the sum of the leaf area of plants above the ground surface per unit area which
is a key indicator reflecting the growth status of plant populations. The establishment
of the “China LAI Cal-Val” and its data publication is a new milestone for the
research on China satellite-ground integration infrastructure. It is a reliable
data infrastructure in meeting the challenges of the LAI data quality. It plays
an irreplaceable role in scientific research in climate change, ecological
environment, and sustainable agriculture.
