摘要局地尺度观测站（LSOS）是2002/03年冷陆过程试验（CLPX）中最小的研究站（0.8公顷），位于弗雷泽中尺度研究区。这是CLPX最密集的测量站点，这里的测量在所有CLPX站点中具有最大的时间分量。在陆地观测卫星上进行的测量旨在对地面遥感仪器观测到的雪、土壤和植被特征进行全面评估。地面微波遥感的目的是收集积雪、土壤和森林上空主动和被动微波光谱特征的时间序列，这与这些特征的密集物理特性相吻合。地基遥感仪器包括在多个微波带宽上工作的调频连续波（FMCW）雷达;地基微波辐射计（GBMR-7）在18.7，23.8，36.5和89 GHz信道上工作; 2003年，一个新的地面遥感仪器被安装在地面。
Abstract The local scale observation site (LSOS) is the smallest study site (0.8 ha) of the 2002/03 Cold Land Processes Experiment (CLPX) and is located within the Fraser mesocell study area. It was the most intensively measured site of the CLPX, and measurements here had the greatest temporal component of all CLPX sites. Measurements made at the LSOS were designed to produce a comprehensive assessment of the snow, soil, and vegetation characteristics viewed by the ground-based remote sensing instruments. The objective of the ground-based microwave remote sensing was to collect time series of active and passive microwave spectral signatures over snow, soil, and forest, which is coincident with the intensive physical characterization of these features. Ground-based remote sensing instruments included frequency modulated continuous wave (FMCW) radars operating over multiple microwave bandwidths; the Ground-Based Microwave Radiometer (GBMR-7) operating at channels 18.7, 23.8, 36.5, and 89 GHz; and in 2003, a...
