for BLS and SLS Series
The DMI-1 option consists of a temperature sensor, a barometric pressure sensor, a small tower and cables to connect the sensors directly to the SPU.

for SLS Series
The DMI-2 option consists of two temperature sensors, a barometric pressure sensor, a small tower and cables to connect the sensors to the SPU. The additional temperature sensor is to measure the temperature gradient.

for SLS Series
The Real-Time Heat Flux Extension contains two temperature sensors, pressure sensors and a combined temperature and humidity sensor for an accurate calculation of CT2 and sensible heat flux for all - unstable and stable - conditions. A data logger allows to connect other sensors provided by the user.

for SLS Series
The Real-Time Evapotranspiration Extension contains net radiation sensors, two soil heat flux sensors, two temperature sensors, pressure sensors, precipitation sensors, and a combined temperature and humidity sensor for determining the evapotranspiration in terms of latent heat through the so-called energy-balance method. A data logger allows to connect other sensors provided by the user.

The Real-Time Basic Extension contains temperature, humidity, and pressure sensors for the calculation of the structure parameter of temperature and in the case of the SLS ES series also the dissipation rate of turbulent kinetic energy. A data logger allows to connect other sensors provided by the user.

for BLS and SLS Series
This set of two Aspirated Radiation Shields can be used with the Real-Time Heat Flux and Evapotranspiration Extensions for higher accuracy in temperature measurements.

for BLS and SLS Series
The Real-Time Sensor Interface Software allows data from sensors from Real-Time Extensions or other weather stations connected to the Signal Processing Unit to be integrated into the SRun software.

for SLS Series
The Crosswind Extension allows of the horizontal wind speed component perpendicular to the optical propagation path.

for BLS and SLS Series
This optional cable can be plugged into the Weather Station Port of the Signal Processing Unit. It can be used to have the BLS or SLS measurement data transmitted in real-time to your equipment.

for BLS and SLS Series
The analog out cable with open wires is optionally available to connect the Analog Out Port of the Signal Processing Unit to an external datalogger or other signal processing equipment.
