Doppler data at Denver (1987)

Doppler radar data were made available to the Denver WSFO beginning in April 1987. The data consisted of reflectivity and velocity PPI images at .2, .7, 1.8, 2.9 and 4.0 degree tilts which were derived from the NCAR CP-2 radar operating in an automatic volume scan mode. Also produced from the Doppler data were four NEXRAD algorithms. These algorithms were of storm identification, storm track, mesocyclone and hail/storm structure. All of the above were presented to the WSFO forecasters via the DAPPE workstations at 3, 6, and 10 minute intervals depending on the mode of operations; e.g., storm, convective surveillance or clear air. All radar data could be viewed with the full DAR^E capabilities, including zoom, roam, animation, and the ability to quickly change color enhancements. This suite of products is not the complete NEXRAD product set, and in particular is lacking any storm cross-section product or precipitation processing products. Nevertheless, this was a large difference for Denver which previously had only a remote KAVOURAS display of the Limon, Colorado WSR-57.

自1987年4月起，丹佛气象服务现场办公室（Denver WSFO）即可获取多普勒雷达数据。该数据集包含由工作于自动体积扫描模式的NCAR CP-2雷达生成的、俯仰角为0.2°、0.7°、1.8°、2.9°及4.0°的反射率与速度平面位置显示器（Plan Position Indicator, PPI）图像。此外，基于该多普勒雷达数据还生成了四项下一代天气雷达系统（Next Generation Weather Radar, NEXRAD）算法，分别用于风暴识别、风暴追踪、中气旋检测以及冰雹/风暴结构分析。上述所有产品均通过DAPPE工作站向丹佛WSFO的气象预报员推送，推送间隔为3分钟、6分钟或10分钟，具体取决于运行模式：例如风暴模式、对流监视模式或晴空模式。所有雷达数据均可通过完整的DAR^E功能进行查看，包括缩放、漫游、动画播放以及快速调整色彩增强效果的能力。该产品套件并非完整的下一代天气雷达系统产品库，尤其缺少风暴剖面产品与降水处理类产品。尽管如此，这对丹佛而言已是巨大的提升——此前丹佛仅能远程查看科罗拉多州利蒙市WSR-57雷达的KAVOURAS显示画面。
