The leaf area index (LAI) serves as a key metric for tracking crop growth and can be integrated into models yield estimation. Although the remote sensing LAI data provide critical foundation monitoring estimating yields, existing datasets often exhibit notable errors due to pixel-level heterogeneity. To improve applicability inversion accuracy of MODIS products in Northeast China (NEC) region, this study upscaled 500-m resolution product 5-km by initially calculating mean value. Then, scale...
Spring frost damage (SFD) is the main meteorological disaster limiting tea industry in region of north Yangtze River (NYR) China. Research regarding an SFD indicator for plants great significance prevention and control spring frosts, as well timely monitoring early warning. Based on daily minimum air temperatures (Tmin) records NYR from 1961 to 2020, Receiver Operating Characteristic curve (ROC) was used evaluate accuracy identification, critical temperature threshold determined by jointly...
Tea (Camellia sinensis) is one of the most dominant economic plants in China and plays an important role agricultural benefits. Spring tea popular drink due to Chinese drinking habits. Although global temperature generally warming, spring frost damage (SFD) still occurs from time time, severely restricts production quality tea. Therefore, monitoring evaluating impact SFD a timely precise manner significant urgent task for scientists producers China. The region designated as Middle Lower...
Current estimates of gross carbon flux tend to ignore the downwelling CO 2 from stratosphere. Observations showed that there is a phase shift between time series for concentration standard isotopologue C 16 O and 18 at Waliguan, China (36°17′N, 100°54′E, 3816 m) several other places. Previous attempts explain have not been satisfactory. Here we show could be explained by air stratosphere, demonstrate this source provides useful tool constraining cycle. Using 3 as proxy...
Spring frost damage (SFD), defined as the disaster during period of newly formed tea buds in spring caused by lower temperature and damage, is a particular challenge for plants (Camellia sinensis), whose capacity to adapt extreme weather climate impacts limited. In this paper, region Middle Lower Reaches Yangtze River (MLRYR) China was selected major plantation study area, focused on concentrated occurrence SFD, i.e., from March April. By employing standard lapse rate air with elevation,...
Starting from the national scale and annual level, potential climate factors are interpolated into 10 km×10 km grid data based on daily set of 1903 weather stations 1961 to 2019 across country, a tea plant distribution dataset consisting 1115 records is established. Using maximum entropy model GIS technology, dominant climatic affecting in mainland China screened according contribution percentage Jackknife method, suitability zoning divided 4 grades: Unsuitable, sub-suitable, suitable...
As a main economic crop in China, tea plant is prone to frost disaster when it germinates early spring. The research progress and achievements of spring are systematically summarized. In southern Yangtze River, the on index risk assessment abundant. for spatio-temporal distribution characteristics disaster, most existing studies based regional scales provincial scales, focusing Southern River. There few reports national scale. Tea can be divided into three categories classification criteria....
Tea plants (Camellia sinensis (L.) Kuntze) are a cash crop that thrive under warm and moist conditions. However, tea becoming increasingly vulnerable to heat damage (HD) during summer growing seasons due global climate warming. Because China ranks first in the world both harvested area total production, monitoring tracking HD timely manner has become significant urgent task for scientists producers China. In this study, spatiotemporal characteristics of evolution were analyzed, method using...
Tea plants (Camellia sinensis (L.) Kuntze) are a cash crop that thrives under warm and moist conditions. However, tea increasingly vulnerable to heat damage (HD) during summer growing seasons due global climate warming. Because China ranks first in the world both harvested area total production, monitoring tracking HD near real-time has become significant urgent task for scientists producers China. The objectives of this study were dynamically monitor critical land surface temperature (LST)...
