Explanation
Please explain in the area below why an STA is necessary:
We were requested by Kennedy Space Centers spectrum management team to file for an STA if we want to use Vaisala Oyj RS41-SGP Radiosondes at our facility.

Purpose of Operation
Please explain the purpose of operation:  The radiosondes were seeking approval for would be used for the Quantifying and Understanding Environmental Turbulence Affecting Lasers (QueTal) project sponsored by the Joint Directed Energy Transition Office. The objective of this project is to collect coherent datasets in coastal/inland environments for testing and validating theories and empirical formulations relevant to optical turbulence characterization and prediction as an additional dataset to the existing dataset of QueTal in the marine and desert environments and provide a better understanding of the nature of atmospheric turbulence and its effects on optical propagation. In the upcoming field testing campaign a tethered balloon, various surface level instruments, SODAR, and two instrumented mobile towers will be deployed at the TISTEF 1km laser range at Kennedy Space Center, FL. These instruments will characterize the refractive index structure constant Cn2 at various heights in the boundary layer. The radiosondes this STA is about will also be deployed using weather balloons to take upper boundary layer data up to 32808 ft, ideally 5 radiosondes deployed per day through the two week campaign totaling to 70. This data alongside planned surface level laser beam profiling will help to build a more rigorous model of Cn2.
