	From [[SSI-28]], we learned that the sensor value fluctuates with the orientation of the payload, so a second flight was conducted on [SSI-30]] with the UV A and UV B sensors, combined with a 10DOF acceleration and orientation sensor. Trough this sensor fusion, the high points of the microWats/cm^2 crest can be correlated the direct illumination of the sun, giving us a more accurate UV value than a simple average, and we will also gain a good understanding of the levels of ambient UV scattering at specific altitudes. This flight also served to validate the data from the previous launch, so that we can account for the effect of atmospheric differences.

	In order understand the exact effect of ultra violet A and B present at different altitudes, a sensor for each UV type was launched on the [[SSI-28]] launch. From the collected 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 was a lot of oscillation in 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, and the new UV intensity data from [[SSI-28]], a new experiment will be done indoors with UV LEDs that emit light at 365 manometers at a constant intencity. This will be to control for and calculate the exact amount of UV that the latex is being exposed to, in order to determine the proportion of UV concentration to natural sunlight at the desired altitude. The independent variable will be the concentration of chemical spray per area, which will be tested against the independent variable of lifespan, in order determine the ideal amount of Anti-UV Scuba spray to apply onto the balloon.
