TBS: Baseline Instruments

 

ARM has a suite of baseline instruments that are typically flown on its tethered balloon system (TBS) missions. Other instruments that may be flown on the TBS are available upon request. Typically, only a subset of the instruments in this second category could be accommodated on a particular mission. In the following table, instruments are designated as baseline or available upon request in the Type column.
