GPM Ground Validation Upper Air Radiosonde OLYMPEX V1

The GPM Ground Validation Upper Air Radiosonde OLYMPEX dataset was collected from October 28, 2015 through January 16, 2016 during the GPM Ground Validation Olympic Mountain Experiment (OLYMPEX) held on the Olympic Peninsula in the Pacific Northwest of the United States. Radiosondes were released from 5 locations: 3 in US - KSLE, KUIL, and NPOL site; and 2 in Canada - ECCC instrument site and CYZT. A total of 651 radiosondes were launched and collected during OLYMPEX from these sites. In addition, Level 4 dropsonde data were reprocessed to match the Level-4 data format and content of the radiosonde files and is also provided here. The dropsondes were released from the NASA DC-8 aircraft during specific flights in December 2015 and are published as the AVAPS dataset. This Upper Air Radiosonde dataset contains Level 0 through Level 4 data containing dew point temperature, pressure, air temperature, relative humidity, horizontal wind speed, vertical wind speed, wind direction, rise or drop rate, and geopotential height measurements. The data files are available in ASCII, ASCII-EOL, and netCDF-3 formats, as well as Skew-T and time series plots in PNG format. The lower level datasets (Level 0 raw data through Level 2 data) are only available upon request from the NASA GHRC DAAC.

GPM 地面验证上层空气无线电探空仪 OLYMPEX 数据集于 2015 年 10 月 28 日至 2016 年 1 月 16 日期间，在美国太平洋西北部的奥林匹克半岛 GPM 地面验证奥林匹克山脉实验（OLYMPEX）期间收集。无线电探空仪从 5 个地点释放：美国 3 个地点——KSLE、KUIL 和 NPOL 站点；加拿大 2 个地点——ECCC 仪器站和 CYZT。在 OLYMPEX 期间，从这些地点共发射并收集了 651 个无线电探空仪。此外，将第 4 级降流探空仪数据进行重新处理，以匹配无线电探空仪文件的第 4 级数据格式和内容，并在此提供。降流探空仪在 2015 年 12 月特定航班中从 NASA DC-8 飞机上释放，并作为 AVAPS 数据集发布。该上层空气无线电探空仪数据集包含从第 0 级至第 4 级数据，包括露点温度、气压、气温、相对湿度、水平风速、垂直风速、风向、上升或下降速率以及位势高度测量。数据文件以 ASCII、ASCII-EOL 和 netCDF-3 格式提供，以及 PNG 格式的 Skew-T 和时间序列图。较低级别数据集（从第 0 级原始数据至第 2 级数据）仅根据请求从 NASA GHRC DAAC 提供。
