• Primarily troubleshooting the anemometers.
• determined that the tower one is outputting and output is being received by LI7550.
• Bottom unit is outputting but all winds are zero through rs232 interface and also the analog interface.
• complicating things a bit, the lower interface box doesn't seem to have the capacity to log digital?? so I'm going to move the tower unit to the forest floor and then rewire the tower for digital.
• that should get something....
• Also there is still closer to 100% snow cover.

• 5/4 update:
  • determined conclusively that bottom anemometer needs service
  • figured out I need a new cable to connect rs232 of new anemometer to 7550 unit.
  • tower still good/ aside from the multiplier issue
    • I figured out that when I apply the coefficients using the LI7200 windows software, the changes are noted on the computer but they aren't applied to the sensor itself. Each time I connect from no program running the sensor modifiers have been reset to original defaults for some reason.

• Next visit:
  • swap out tower anemometers with new ones
  • replace wind monitor
  • check on a better if there is a mount available for aligning anemometer to true north.
  • took some photos of the air blower deals so I can look for replacements online
• need to order the rs232 interface cable for the 7550 for the forest floor unit.
• need to ask Gill for the PIC unit, too. which is an interface for communicating with anemometers in the office.
  • start planning out new system with additional PAR etc measurements.
• SDI sensors can be connected to snow profile logger
• the nuts & bolts for gill forest unit are in a cardboard box labeled 'installation kit' on the shelf with UPS
