The High Altitude Research Platform (HARP) IR-UV spectrometer, Visible light intensity, and Ultraviolet types A (400-315 nm), B (315-280 nm), and C (280-100 nm) Intensity project is a high altitude balloon experiment designed to study the absorption spectrum of the gases in our atmosphere up to 35 km and to capture the solar blackbody spectrum with its absorption lines. Our sensor system includes three UV photodiodes, a visible light sensor and Ocean Optics spectrometer which are capable of measuring wavelengths over a range of 200-1025 nm at a resolution of ~1.7-2.1nm. We secured the sensor to the pod with an assembly that we designed in Solidworks and fabricated through the use of a 3D printer. In addition, we designed photocurrent amplifier for the UV photodiodes and fabricated a PC board to carry it. We individually and cross analyzed the data from each of the sensors. Documentation of the fully functional system and analysis of UV profiles may be used to reproduce the experiment for students in courses such as chemistry or astronomy without the use of the spectrometer.
