Subject: | MAO/SMPS/S1 - Insects clogged nafion dryer and SMPS impactor |
DataStreams: | maoaossmpsS1.a1 |
Description: | During this time period the SMPS total concentration was low relative to the cpcf and cpcu concentrations. Upon troubleshooting and examination of components it was discovered that a number of small insects had clogged the nafion dryer and SMPS impactor. The counts may have been lowered due to additional losses from bugs. |
Suggestions: | The concentrations are lower, but seem to trace diurnal patterns in total number concentrations. It is unclear what size dependent counting efficiency could have resulted from this. Use data with caution |
