In-season maize yield prediction in Northeast China: The phase-dependent benefits of assimilating climate forecast and satellite observations Agric. For. Meteorol. (IF 5.6) Pub Date : 2024-09-24 Chenxi Lu, Guoyong Leng, Xiaoyong Liao, Haiyang Tu, Jiali Qiu, Ji Li, Shengzhi Huang, Jian Peng
Various yield forecasting methods have been reported in literature, but the benefits of assimilating seasonal climate forecasts and satellite observations for in-season yield forecasting during different growth stages have rarely been examined using machine learning. By synthesizing census yields, seasonal climate forecasts (SCF) and satellite-based gross primary production (GPP), this study develops

Altitudinal adjustment of leaf spectral reflectance in broad-leaved species on the Qinghai-Tibetan Plateau Agric. For. Meteorol. (IF 5.6) Pub Date : 2024-09-24 Xinran Ke, Huixing Kang, Tong Guo, Yan Zhang, Tianyu Zheng, Yixin Ma, Xiruo Wang, Yanhong Tang
Leaf spectral reflectance is a crucial indicator of leaf physiology both in eco-physiology and remote sensing. To assess how alpine plants acclimate or adapt to altitudinal environments, we examined leaf optical properties at wavelengths from 280 to 1100 nm in 797 leaves of 38 broad-leaved herbaceous species along an altitudinal gradient from 3200 m to 4400 m on the northeastern Qinghai-Tibetan Plateau
