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.

Mission goal

LEMON 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.

Growing branches for a spaceborne LEMON LIDAR development
  • Roadmap analysis
  • Sub-units environmental testing
  • Critical components radiation testing
  • Future mission proposals
