摘要云和地球辐射能量系统（CERES）使用Terra和Aqua卫星上的一套仪器，结合分析的天气数据和地表条件信息来估计地表辐射通量。CERES对Terra卫星的估计值与研究船（RV）Wecoma和托马斯G. 2000- 2003年期间，在俄勒冈州海岸外进行巡航的汤普森辐射计。为了评估船上的测量结果，对辐射计的观测结果进行了分析，以确定无云条件，其特点是辐射通量相对稳定，持续时间为10 -2 h。无云条件下的通量进行了比较，从分析气象场的时间和位置的测量和宽带辐射传输模型的温度和湿度的配置文件计算。对于沿着俄勒冈州海岸的夏季条件，并假设海洋气溶胶具有0.55 μm的光学厚度为0.05，m...
Abstract Clouds and the Earth’s Radiant Energy System (CERES) uses a suite of instruments on the Terra and Aqua satellites combined with analyzed weather data and information on surface conditions to estimate surface radiative fluxes. CERES estimates for the Terra satellite were compared with measurements of the surface radiative fluxes collected with the research vessels (RVs) Wecoma and Thomas G. Thompson radiometers for cruises off the Oregon coast undertaken during 2000–03. To assess the shipboard measurements, the radiometer observations were analyzed to identify cloud-free conditions characterized by ∼1–2 h of relatively stable radiative fluxes. Fluxes for the cloud-free conditions were compared with those calculated using profiles of temperature and humidity from analyzed meteorological fields for the times and locations of the measurements and broadband radiative transfer models. For summertime conditions along the Oregon coast, and assuming a marine aerosol having 0.55-μm optical depth of 0.05, m...
