资源简介:
The overarching goal of the California Underwater Glider Network is to sustain baseline observations of climate variability off the coast of California. The technical approach is to deploy autonomous underwater gliders in a network to provide real-time data.The CUGN uses Spray underwater gliders making repeated dives from the surface to 500 m and back, repeating the cycle every 3 hours, and traveling 3 km in the horizontal during that time. The CUGN includes gliders on three of the traditional cross-shore CalCOFI lines: line 66.7 off Monterey Bay, line 80 off Point Conception, and line 90 off Dana Point. The glider missions typically last about 100 days, and cover over 2000 km, thus providing 4-6 sections on lines extending 300-500 km offshore. Since 2005 the CUGN has covered 200,000 km over ground in 28 glider-years, while doing 90,000 dives.cdm_data_type = TrajectoryProfileVARIABLES:trajectory (Trajectory Name)wmo_idtime (Profile Time, seconds since 1970-01-01T00:00:00Z)latitude (Profile Latitude, degrees_north)longitude (Profile Longitude, degrees_east)profile_idtime_uv (Depth-averaged Time, seconds since 1970-01-01T00:00:00Z)lat_uv (Depth-averaged Latitude, degrees_north)lon_uv (Depth-averaged Longitude, degrees_east)u (Depth-averaged Eastward Sea Water Velocity, m s-1)v (Depth-averaged Northward Sea Water Velocity, m s-1)latitude_qc (latitude Variable Quality Flag)longitude_qc (longitude Variable Quality Flag)time_qc (time Variable Quality Flag)depth (m)depth_qc (depth Variable Quality Flag)pressure (Sea Water Pressure, decibars)pressure_qc (pressure Variable Quality Flag)...

加州水下滑翔机网络(California Underwater Glider Network,简称CUGN)的总体目标是维持加利福尼亚沿岸气候变率的基准观测。其技术方案为布设自主水下滑翔机组网以获取实时观测数据。CUGN采用Spray水下滑翔机(Spray underwater glider),该机型会反复在海面至500米深度间往返下潜与上浮,每3小时完成一个循环周期,此期间水平航行距离可达3千米。CUGN的滑翔机部署于三条传统跨岸CalCOFI测线:蒙特雷湾外的66.7号测线、康塞普西翁角外的80号测线,以及达纳角外的90号测线。滑翔机单次任务周期通常约为100天,累计航程超过2000千米,因此可在向海延伸300至500千米的测线上完成4至6个观测断面。自2005年以来,CUGN已在28个滑翔机作业年度内累计地面航程达20万千米,累计完成9万次下潜作业。 公共数据模型数据类型(cdm_data_type)= 航迹廓线(TrajectoryProfile) 变量列表(VARIABLES): trajectory(航迹名称) wmo_id time(廓线时间,即自1970-01-01T00:00:00Z以来的秒数) latitude(廓线纬度,北纬度数) longitude(廓线经度,东经度数) profile_id time_uv(深度平均时间,即自1970-01-01T00:00:00Z以来的秒数) lat_uv(深度平均纬度,北纬度数) lon_uv(深度平均经度,东经度数) u(深度平均东向海流速度,单位:m·s⁻¹) v(深度平均北向海流速度,单位:m·s⁻¹) latitude_qc(纬度变量质量标记) longitude_qc(经度变量质量标记) time_qc(时间变量质量标记) depth(单位:米) depth_qc(深度变量质量标记) pressure(海水压力,单位:分巴) pressure_qc(压力变量质量标记) ……(另有21个变量)
