CSU array-averaged analysis products
These data products were created by objectively analyzing upper-air sonde data onto a regular 1-degree, 25-hPa grid using multiquadric interpolation. The gridded data fields were then averaged over the Northern Sounding Array (NSA) and Southern Sounding Arrays (SSA). The NSA analyses were strongly modulated by MJO signal while SSA analyses were modulated more by ITCZ convection. Default input files of Indian Ocean:
