TSI APSS 3321 issues

Hi, do we have an activity already to collect in our community and foreward to TSI issues with TSI APSS 3321 and how we cope with this on the long-term? We discussed in an AIS meeting already 1-2 years ago, that someone (the NF-representative AIS - Costas?) would set up an inventory of defects with ...

Re: PM10 + Whole air inlet combination

Thank you for your answers 1.5 years ago! Meanwhile for Hohenpeissenberg we plan with TROPOS to implement an inlet train whole-air + subsequent PM10, which should, at least in theory, impose no break to our time series for the data fraction taken under 'no fog' conditions and save us much cleaning e...

Experiences with upgraded TOF-ACSM X?

Hi, has anyone already experience with the new TOF-ACSM X, Benjamin showed at the ACTRIS innovation meeting on 2 June? Is it already or will it soon be on the ACTRIS white list of instruments, because it is more or less the same instrument as the hitherto TOF-ACSM? If not yet, what is the proceduce ...

PM10 + Whole air inlet combination

Hi all, as Hohenpeißenberg station is in clouds/fog for >5-10% of the time (~10% with visual range <200m) we are supposed to change our current PM10 inlet (installed 2003, DIGITEL, 170 l/min) to whole-air. In order to minimize rupture of time series (as of 1995) and pollution of instruments by polle...
