In order to collect data on the levels of ultra violet A and B present at different altitudes, a sensor for each UV type was launched on [[SSI-28]]. From the data, it can be concluded that there is much more UV A than UV B, and it does in fact increase with altitude, reaching a max value of 1323 microwatts/cm^2 for UV A and 292 microwatts/cm^2 for UV B. In addition, there is a lot of noise in the values, with a corresponding oscillation of values, which is due to the sensor being on one side, and the payload spinning during its flight. Thus, the value where the sun is directly facing the latex would correspond to the high part of the wave.

As  result of the positive results of the chemical protection tests, a new experiment will be done indoors with UV LEDs that emit 365 manometers. This will be to control for and calculate the exact amount of UV that the latex is being exposed to. The independent variable will be the concentration of chemical spray per area, in order determine the ideal amount to apply onto the balloon.
