论文摘要
自2016年以来，Alta Project一直处于活跃状态，在LBT天文台站点提供了大气参数的预测，例如温度，风速和方向，相对湿度和可累积的水蒸气以及光学湍流参数，例如观察，Wavefront Coolence Time和Insoplanatic和Insoplanatic和Insoplanatic and Insoplanatic，以支持LBT的最终夜间守流的目标。除了预测之外，在这几年中，Alta一直在收集有关大气条件的统计数据，这些条件可用于对位于亚利桑那州格雷厄姆山顶部的望远镜地点的气候进行非常准确的表征。这种表征可以用于预测模型的优化和校准，也可以作为模型验证的参考。这些参数的气候学被认为是ALTA的进一步输出，它将随着时间的推移在网站上升级，并且可以在短时间内和长时间范围内提出证据趋势。在这项贡献中，我们介绍了与地面天文学相关的所有大气参数的气候描述，以便向科学界提供LBT的BServing条件的强大参考。该研究是使用DIMM和大气传感器在几年内提供的现场测量值进行的，并在望远镜遥测数据中提供。
ALTA project has been active since 2016, providing, at LBT observatory site, forecasts of atmospheric parameters, such as temperature, wind speed and direction, relative humidity and precipitable water vapor, and optical turbulence parameters, such as seeing, wavefront coherence time and isoplanatic angle with the final goal to support nightly the science operation of the LBT. Besides to the forecasts, during the years ALTA has been collecting statistics on the atmospheric conditions which can be used to draw a very accurate characterization of the climatology of the telescope site located on top of Mount Graham, Arizona. Such characterization can be used both for the optimization and calibration of the forecast model and as a reference for a model validation. The climatology of these parameters is conceived to be a further output of ALTA that will be upgraded on the website with time and it will be able to put in evidence trends at short as well as long time scales. In this contribution we present a climatological description of all the atmospheric parameters relevant for ground-based astronomy in order to provide to the scientific community a robust reference of the bserving conditions at LBT. The study is performed using on-site measurements provided by DIMM and atmospheric sensors over several years and made available in the telescope telemetry data.
