Aeronomical and Meteorological Research at Jicamarca Radio Observatory

秘鲁利马附近的Jicamara射电观测站是第75个子午链非相干散射观测站的赤道锚。它的运行对一些联合实验至关重要，这些实验追踪能量、动量和质量从地球高层大气的极地到赤道地区的流动。磁层与极地电离层和热层高纬度相互作用的全球响应是一个极具科学兴趣的课题，也是1980年S和1990年S研究的一个关键领域。例如，Jicamara射电天文台是美国国家科学基金会新的大气区域耦合、能量和动力学计划的关键。该项目将帮助支持Jicamara射电观测站的运作，并为将在该设施开展的实验研究方案提供资金。Jicamara是四个雷达之一，形成了从格陵兰岛到秘鲁的子午链，特别适合研究上述全球能源问题。它将单独并与其他雷达和光学仪器一起观测大气响应(即密度、温度、风和电场对高纬度能量输入的变化)。除雷达链实验外，还将继续在以下主要领域进行研究：(1)中性大气的动力学(对流层、平流层和中间层中的风、波和湍流)；(2)赤道电磁场中的等离子体湍流；(3)150公里回波区：(4)赤道扩展F(ESF)不规则；(5)平静期和扰动期E区和F区的电场；(6)通过加热赤道电急流人工产生甚低频波。

The Jicamarca Radio Observatory near Lima, Peru serves as the equatorial anchor of the 75th meridian chain of incoherent scatter observatories. Its operation is crucial to a number of joint experiments which trace the flow of energy, momentum and mass from the polar to the equatorial regions of the earth's upper atmosphere. The global responses to the high latitude interactions of the magnetosphere with the polar ionosphere and thermosphere are a subject of great scientific interest and a key area of study in the 1980's and 1990's. The Jicamarca Radio Observatory, for example, is critical to the new NSF initiative CEDAR (Coupling, Energetics and Dynamics of Atmospheric Regions). The project will help support the operation of the Jicamarca Radio Observatory and provide funds for a program of experimental research to be conducted at that facility. Jicamarca is one of four radars, forming a meridional chain from Greenland to Peru that are particularly well sited to examine the global energy questions indicated above. It will observe, alone and in combination with the other radars and optical instruments the atmospheric response (i.e., changes in densities, temperatures, winds, and electric fields to high-latitude energy inputs. In addition to the radar chain experiments, research will continue in the following major areas: (1) the dynamics of the neutral atmosphere (winds, waves, and turbulence in the troposphere, stratosphere, and mesosphere); (2) plasma turbulence in the equatorial electroject; (3) the 150km echoing region: (4) equatorial spread F (ESF) irregularities; (5) electric fields in the E and F region during quiet and disturbed periods; and (6) the artificial generation of VLF waves by heating the equatorial electrojet.
