Daily Weather Forecast Mirai Updates! Ron Brown Updates!

Commentary:

It's getting crowded around here with the arrival of Jason Cole, Ed Westwater and others. We've been playing a game of Twister in all the vans; don't know who's winning.

Colin Schulz has been training observers and all others who are interested (which is just about everyone) on the Qfax and Emwin systems.

We expect to begin getting the Hawaii forecast and commentary starting tomorrow morning. At least we hope so, since the small triangle pattern starts tomorrow. (The ships will move after sundown tonight.) We'll need to watch for a nonconvective period to bring the ships together for their close comparison. Maybe I should have paid more attention in forecasting class. I did bring my lucky quarter, though, so I have a 50-50 chance...

Visual Observations:

The day started out overcast, but then became sunny. We had a rousing shower this afternoon. It has been abundantly cloudy. The skiers calmed down from yesterday's taunting after I told them they could make a snowman (when it snows) by packing Conner inside. They are standing around eagerly watching the skies.

Instrument Status:

Atmospheric Radiation and Cloud Station (ARCS2) Site Instruments:

All instruments are performing well. The millimeter cloud radar (MMCR) was taken offline for maintenance for a few hours today. The whole sky imager (WSI) was taken offline for about 30 minutes to finish up the final nut tightenings from a previous repair.

Nauru99 Ancillary Instruments:

The hemispheric sky imager (HSI) camera has been replaced and the system is working. The portable radiation package (PRP), Cimel, rotating shadowband radiometer (RSR) and top-side met are all doing well.

The Pennsylvania State University (PSU) sun photometer and cavity radiometer are both being run in between raindrops. The Qfax and EMWIN systems are doing well, except for a minor glitch this morning.
