[5] The 2001 sprite campaign in Taiwan was conducted between April and August of 2001. The two observation locations for this campaign were the Ali Mountain Weather Station (AMWS, 2413 m) and the campus of National Cheng Kung University (NCKU, 50 m). The camera systems used in this campaign consisted of WAT-902H/Neptune CCDs, Sigma 20 mm/f1.8 lens, Nikon 50 mm/f1.4 lens, and SONY DCR-PC5 digital recorders. When equipped with a 20 mm lens, the field of view (FOV) of the camera is 18.5°(H) by 13.8°(V). With a 50 mm lens, the FOV is 7.5° by 5.6°. The cameras were operated at interlaced frame mode with standard video rates at 30 frames per second.
[6] The internal clocks of the digital recorders, after being synchronized to the GPS time, were used to generate the time codes for the images. In the SONY DCR-PC5 digital recorder, the time codes are stored in a separated memory buffer, so they will not interfere with the sprite images and can be inserted as needed.
