The LEMON tree is growing with SpaceTech‘s FRUIT
We are proud to announce being part of the Lidar Emitter and Multispecies greenhouse gases Observation INstrument project - short LEMON, a H2020 funded activity. The LEMON consortium consists of 8 partners from 4 different countries, including academic experts, research centres and SME partners.

LEMON mission goalLEMON shall deliver a new Differential Absorption Lidar (DIAL) sensor concept in order to measure greenhouse gases and water vapour from space and demonstrate the concept in an airborne campaign. |
LEMON features
The innovative LEMON concept is based on a versatile, efficient multispecies Lidar emitter:
- development of only one space instrument for CO2, CH4, H2O, HDO measurements necessary
- simultaneous CO2+H2O or H2O HDO measurements possible

SpaceTech development for LEMON
Being part of the LEMON project, STI was elected to develop, manufacture and deliver the so-called LEMON FRUIT which consists of a wavemeter, controlling unit, tunable absolute reference laser and heterodyne beating detection. In addition, SpaceTech is responsible for the system planning and evaluation of a future spaceborne LIDAR.
