Executive Summary

We submit the Nubo Sphere continuous monitoring solution to annual testing at University of Colorado’s Methane Emissions Technology Evaluation Center (METEC) facility. The results of the 2022 Advanced Development of Emissions Detection (ADED) testing campaign are available here and you will find the comprehensive report on Sensirion’s performance, containing further details, in the appendix. METEC recently completed the 2023 testing campaign. Based on pointed development of our solution over the past year, we expect an improvement on our 2022 ADED performance. In preparation, we have prepared this commentary on our 2022 ADED test results. This should assist readers in interpreting our 2022 performance and discerning improvements in our 2023 performance.
