The EarthCARE Commissioning Calibration and Validation Campaign in Ottawa (ECALOT) was a dedicated airborne and surface-based campaign designed to support the calibration and validation of Level 1 and Level 2 products from the EarthCARE satellite mission. The campaign was conducted between October 2024 and March 2025 in eastern Canada, primarily in the regions surrounding Ottawa and Montreal. Airborne observations were carried out using the National Research Council Canada (NRC) Convair-580 research aircraft, equipped with remote sensing instruments analogous to those flown on EarthCARE, including a nadir\u002Fzenith\u002Fside-looking 94 GHz cloud radar system with Doppler capability and zenith\u002Fnadir-pointing 355 nm elastic lidars, together with a comprehensive suite of in situ cloud and aerosol probes. Complementary surface-based observations were obtained at a primary site at the Ottawa Macdonald-Cartier International Airport and two additional climate sentinel stations in the Montreal region, providing continuous ground-based reference measurements of surface radiation, atmospheric thermodynamic profiles, precipitation, and other meteorological variables. A total of seven research flights were conducted, sampling a range of mid-latitude continental cloud conditions, including stratocumulus, multilayer cloud systems, and nimbostratus associated with liquid- or solid-phase precipitation. The ECALOT sampling strategy was designed to integrate airborne and surface-based in situ and remote-sensing observations collected along and offset from EarthCARE’s ground track, while accounting for temporal offsets relative to the satellite overpass. Together, the ECALOT campaign provides coordinated multi-platform observations that enable evaluation of active sensor measurements, radar-lidar-imager synergy, representation of liquid, ice and mixed-phase clouds, three-dimensional scene construction, and radiative closure across EarthCARE’s data processing chain, while also providing observational constraints for improving the representation of mixed-phase clouds and their radiative effects in numerical models.","摘要。渥太华EarthCARE调试校准与验证 campaign（ECALOT）是一项专门设计的机载与地基联合观测活动，旨在支持EarthCARE卫星任务一级和二级产品的校准与验证。该活动于2024年10月至2025年3月在加拿大东部开展，主要集中在渥太华和蒙特利尔周边地区。机载观测使用加拿大国家研究委员会（NRC）的Convair-580研究飞机，搭载了与EarthCARE卫星上类似的遥感仪器，包括具有多普勒能力的天底\u002F天顶\u002F侧视94 GHz云雷达系统，以及天顶\u002F天底指向的355 nm弹性激光雷达，并配备了全面的原位云和气溶胶探测设备。在渥太华麦克唐纳-卡蒂埃国际机场的主站点以及蒙特利尔地区的两个额外气候哨兵站获取了配套的地基观测数据，提供地表辐射、大气热力学廓线、降水及其他气象变量的连续地基参考测量。共执行了七次研究飞行，采样了多种中纬度大陆云条件，包括层积云、多层云系以及与液态或固态降水相关的雨层云。ECALOT的采样策略旨在整合沿EarthCARE地面轨迹及其偏移方向收集的机载和地基原位与遥感观测，同时考虑相对于卫星过境的时间偏移。总体而言，ECALOT活动提供了协调的多平台观测数据，能够评估主动传感器测量、雷达-激光雷达-成像仪协同、液态、冰态和混合相云的表征、三维场景构建以及EarthCARE数据处理链中的辐射闭合，同时为改进数值模式中混合相云及其辐射效应的表征提供观测约束。",null,"OpenAlex","2026-09-09T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"EarthCARE卫星定标验证的航空与地面联合观测论文，属大气遥感与气象领域，与三农、农业信息化无直接关联，不建议进入每日精选。",[19],{"name":10,"url":6},[21,22,23,24],"遥感","卫星定标","云雷达","大气观测","10.5194\u002Fegusphere-2026-5347",{"doi":25,"openalex_id":27,"authors":28,"venue":9,"cited_by_count":15,"oa_url":79,"card":80,"direction":84,"ingested_from":86},"W7212065193",[29,32,34,36,39,41,44,47,50,52,55,58,60,63,66,68,71,73,75,77],{"name":30,"orcid":31},"Zhipeng Qu","https:\u002F\u002Forcid.org\u002F0000-0002-7895-6470",{"name":33,"orcid":9},"Cuong Nguyen",{"name":35,"orcid":9},"Paloma Borque",{"name":37,"orcid":38},"Alexei Korolev","https:\u002F\u002Forcid.org\u002F0000-0003-3877-8419",{"name":40,"orcid":9},"Howard W.
