|Weather mast||temperature, relative humidity, wind direction, wind speed in 2 and 10 m above ground||PT100 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|
|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|
| 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|
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).
| 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 .|
