overview: SPURS-2, the second of the SPURS field campaigns took place in a fresh and rainy area of the eastern Tropical Pacific in the Fall of 2017. Seventy nine upper-air soundings were taken in support of the SPURS-2 cruise and first deployment of the Colorado State University Sea-Pol radar. read_edt.f95 - fortran program for reading edt (L0) ASCII data read_upaL2_eol.f - fortran program for reading L2 and L3 ASCII data read_upaL4.f - fortram program for reading L4 ASCII data Version 0 starts at 19 m using surface data at this level.
