Overcast skies early in the morning, which cleared by late morning, giving way to mostly cloudy skies by the afternoon with some haze. IOP 5 started at noon today, which the PIs are calling a "Moisture surge" IOP. ~12 U of U students will be visiting sites tomorrow afternoon with PI Sebastian. The outreach event scheduled for Friday with ~60 junior high students has been moved to the ISS1 site.
ISS1 – All systems still running nominally. Profiler status this morning: @ 0936 100m: 4.70A @ 50V & 1.842A @ 32V, and @0933 150m rass: 3.94A @ 50V & 1.891 A @ 32 V. It is interesting that the driver amplifier current increases slightly when running in the 150m mode while the HPA current decreases (as expected because of lower duty cycle).
ISS2 – Isabel cleared out the extra logins and addressed the concerns about fs_/ and fs_/boot directories issue on iss2. Bill had me reset the cell modem used with the Purple aerosol detector, though I also power cycled the Cradlepoint after thinking that was the modem. The modem has also been relocated to the back of the base trailer, just to the left of the soil sample oven, to improve the WiFi connection with the Purple aerosol sensor and/or the modem's cell connection. After which, all systems functioning nominally.
ISFS – Went with Jacquie to the Lake Creek tomorrow to swap out the EC100 and take a third soil sample for that site. Changing out the EC100 did not solve the intermittent issue with the sonic not reporting. Both EC100s showed the sonic LED blinking from green to red, so the issue is with the anemometer. During the soil sample collection, the corer was dented in by a rock that hit just outside the edge.
Soundings – Soundings were launched at 2:01 and 4:15 today. At the 2:01 sounding, another balloon had a pinhole leak, so a second balloon was used. We emptied one helium container with the first launch and the tank we connected to for the second launch was also nearly depleted though not marked with orange tape.
