The increased frequency of sonde launches throughout the experimental period provided better diurnal understanding of the thermodynamic profiles, and thus a better representation within the variational analysis dataset. (arm.gov)
Taking advantage of the expected deployment of a C - POL scanning precipitation radar and an ECOR surface flux tower at the Manus ARM site, we proposed to increase the number of sonde launches to 8 / day starting in about mid-October of the field experiment year, which is climatologically a period of generally suppressed conditions at Manus and just prior to the climatologically strongest MJO period.

Researchers supplement the continuous observations with guest instruments during field research campaigns or by requesting increases in the frequency of measurements, such as sonde launches. (arm.gov)
