Subject:
NSA/MPL/C1 - Diode failure
DataStreams:nsamplC1.a1, nsamplpsC1.a0
Description:
On 3/25, the energy monitor on the MPL dropped from 11 microjoules per second to 2 
microjoules per second.  We determined the problem was the diode; it reached the end of its 
lifetime. A replacement was sent.  Data quality returned to normal.
Suggestions: 
No work around is available.
Measurements:nsamplpsC1.a0:
  • Laser output energy per pulse(energy_monitor)
more
nsamplC1.a1:
  • Aerosol volume backscattering coefficient at 355 nm(backscatter)
  • Laser output energy per pulse(energy_monitor)
