| Subject: | ENA/AOS/C1 - Dry air supply intermittently not working |
| DataStreams: | enaaoscpcfC1.a1 |
| Description: | Pentras dry air supply intermittently not working. Dry air missing for the humidigraph and the HT-DMA. Dry air supply for those instruments partially replaced by regular undried compressed air, lowering the delivery pressure. No direct effect on other instruments seen. |
