Subject:
SGP/AOS/C1  - PSAP Flow Rate Change
DataStreams:sgpaosC1.a0
Description:
The AOS PSAP flow rate was reduce due to data becoming noisy at the end of each weekend, 
probably due to the decrease in the dynamic range of the instrument experienced when the 
filter is heavily loaded.

The flow rate of the PSAP was decreased from its previous nominal value of 0.90 standard 
liters per minute to 0.75 standard liters per minute on 5/26/98 at 1910 GMT.  This should 
lessen the aerosol deposit buildup at the end of the weekends
