Subject:	ASI/SEBS/M1 - Pre-deployment data
DataStreams:	asisebsM1.b1
Description:	All data is before the official start of the IOP on 1 June 2016. Data may be affected by changes to instrument settings and people nearby. The first half-hourly average for the SEBS during June 1 is time-stamped 0030.

Subject:	ASI/SEBS/M1 - Soil Temperature 1 Spikes
DataStreams:	asisebsM1.b1
Description:	Soil temperature 1 spiked to unreasonable values at times, a result of a faulty multiplexer.
Measurements:	asisebsM1.b1: Soil temperature mean 1(soil_temp_1) surface_soil_heat_flux_1 energy_storage_change_1 Average soil heat flow at the surface(surface_soil_heat_flux_avg)

Subject:	ASI/SEBS/M1 - Soil temperatures missing
DataStreams:	asisebsM1.b1
Description:	Soil temperatures were missing because of a loose connection on a multiplexer.
Measurements:	asisebsM1.b1: Soil temperature mean 1(soil_temp_1) Soil temperature mean 3(soil_temp_3) Soil temperature mean 2(soil_temp_2) surface_soil_heat_flux_1 energy_storage_change_2 energy_storage_change_1 surface_soil_heat_flux_3 energy_storage_change_3 surface_soil_heat_flux_2 Surface energy balance(surface_energy_balance) Average soil heat flow at the surface(surface_soil_heat_flux_avg)

Subject:	ASI/ECOR/M1 - Latent Heat and CO2 Fluxes Often Incorrect
DataStreams:	asi30ecorM1.b1
Description:	A cable problem, and sometimes precipitation/fog/dew, caused the latent heat flux and CO2 flux to be incorrect.
