Another calm mostly cool clear day, with a little scattered cirus and some haze. The PIs have called a non-fog IOP for 24 hours starting at noon tomorrow (Sunday 16 Jan).
The big news today was the installation of the quick look plots on the web site (thank you Isabel!). The plots are available at:
- ISS1 Preliminary plots (wind profiler, RASS, CL51, surface met, webcam)
- ISS2 Preliminary plots (soundings, wind lidar, CL61, surface met, webcam)
There are still some bugs and gaps, but most plots (including sounding Skew-T plots) are available now, and more will be available in the coming days. One interesting feature is a disturbance in the pressure trace around 13 UTC which the university folks say appears to be from the Tonga volcanic eruption last night.
Besides work on various aspects of the plotting and web pages, other tasks worked on included installation of a microseven web camera at ISS1 pointed at the Deer Creek reservoir, tweaking of the winds and RASS processing on the Modular Profiler, and tidying up at the sounding trailer.
During the sounding this afternoon (4:15pm, 2315 UTC), the sounding software didn't pick up the surface met data (although the DSM reports polling from the sounding system), and later closed during the sounding. Upon restarting the software a few minutes later, it didn't appear there was any data was missing.
The Modular Profiler was getting winds to the 1.5 to 2 km level, lower than recent days apparently due to a dry layer aloft as can be seen in this afternoon's sounding. In winds mode, the power draw at 22UT was 2.63A on the 50V supply and 1.75A on the 31V supply. In RASS mode the draw was 2.88A and 1.89A on the 50V and 31V supplies.
