AWIPEV Atmosphere Observatory

At the AWIPEV Atmosphere Observatory, long-term measurements of atmospheric thermodynamics, clouds, aerosols and trace gases are operated.

Information on the respective AWI long-term observation (LTO) data series is described here.

Weather masttemperature, relative humidity, wind direction, wind speed in 2 and 10 m above groundPT100 temperature sensors, Vaisala XXX humidity sensors, and Thies Clima classic combined wind sensors are installed in 2 and 10 m above ground.RiS Project 6817
>> Data
Surface radiation Net radiation components (SW up, SW down, LW up, LW down), direct and diffuse radiation Ventilated CMP22 pyranometers, CGR4 and Eppley PIR pyrgeometers monitor the downward and upward radiation components. Ris Project 2350
The measurements contribute to the Baseline Surface Radiation Network (BSRN). Data are accessible upon registration with BSRN (www.bsrn.awi.de)
Ceilometer Cloud base height Pulsed 910nm diode laser instrument (Vaisala CL51) that detects the base height of cloud layers up to 13 km. RiS Project 6817
>> Data
Radiosonde Vertical profiles (0 - 30km) of temperature, pressure, relative humidity, wind speed and direction The radiosonde (Vaisala RS41) ascents with a helium-filled balloon while transmitting the measured data to the ground station. RiS Project 1118
>> Data
The Ny-Alesund radiosonde data also contribute to the GCOS Reference Upper-Air Network [GRUAN].
Ozone sonde Vertical profiles (0-30 km) of ozone concentration The ozone concentration is detected by an electrochemical cell passed through by a defined flow of ambient air. The ozone sonde is launched together with a radiosonde on a helium-filled balloon. RiS Project 1322
The data contribute to the Network for the Detection of Atmospheric Composition Changes (NDACC).

Sun Photometer Aerosol optical depth The sun photometer is a small telescope that automatically tracks the sun in absence of clouds. It measures the aerosol optical depth (AOD) in several wavelengths between 360nm to 1024nm. RiS Project 2353
Star Photometer Aerosol optical depth (during polar night) The star photometer is a telescope that uses star light during the dark season to measure the aerosol optical depth (AOD) in several wavelengths. RiS Project 2353
"KARL" Koldewey Aerosol Raman Lidar Vertical profiles of aerosol backscatter coefficient A pulsed laser is emitted to the atmosphere where the light is scattered back by small particles (aerosols) and droplets. RiS Project 2399

Micropulse Lidar (MPL) Vertical profiles of aerosol and cloud particle backscatter A pulsed laser is emitted to the atmosphere where the light is scattered back by small particles (aerosols) and droplets. RiS Project 3186.
The data contribute to the NASA Micro-Pulse Lidar Network (MPLNET).
>> Data
Doppler Lidar (WindCube) Vertical profiles of wind (up to ~1km) The wind lidar uses particles (aerosol, clouds) as a tracer to measure the wind. It runs automatically 24/7 and provides the 3D wind field up to approx. 1km altitude. However, the effective range depends on the visibility.RiS Project 6525 .
