Common Sampling Objects

In all cases, the sampling geometry can also be provided as part of the SensorML description, and as a sampling feature.

Profiles

Fixed Vertical Profile

• Examples

  • Fixed atmospheric profiler/sounder
  • Oceanography profiler on moorings (CTD, ADCP)

• Output 1: Profile Shape

  • Profile base location (lat/lon/alt)
  • Array of bin depths or altitudes
  • Only updated if instrument is moved or number/positions of bins is changed

• Output 2: Profile Data

  • Array of measured values
  • Updated every time a new profile is acquired

Mobile Vertical Profile (sounder on ship or ground vehicle)

• Examples

  • Atmospheric profiler/sounder on vehicle
  • Oceanography profiler on ships (ADCP)

• Output 1: Profile Shape

  • Array of bin depths or altitudes
  • Only updated if number/positions of bins is changed

• Output 2: Profile Data

  • Profile base location (lat/lon/alt)
  • Array of measured values
  • Updated every time a new profile is acquired

Fixed Rotating Profile

• Examples

  • Doppler radar at fixed station (Nexrad)

• Output 1: Profile Shape

  • Profile base location (lat/lon/alt)
  • Array of bin radial distances
  • Only updated if equipment is moved or number/positions of bins is changed
  • May change if instrument has several modes

• Output 2: Profile Data

  • Mode ID
  • Profile direction (azimuth/elevation)
  • Array of measured values

Sampling Curve

• Output 1: Profile Shape

  • Array of sample locations
  • Only updated if instrument is moved or number/locations of samples is changed

• Output 2: Profile Data

  • Array of measured values
  • Updated every time a new profile is acquired
