SGP/EBBR/E18  - Water in Net Radiometer; Surface Fluxes are Incorrect

The net radiometer top dome was punctured by migrating birds.  This alone does not cause 
incorrect net radiation measurements.  However, when it subsequently rains, water collects 
in the bottom dome, causing the net radiation measurements to be too large during the 
day and too small at night.

SGP/EBBR/E18 - metadata corrections

On 20050723, a series of metadata corrections and additions were completed.  These 
metadata changes apply to all EBBR.E18 data collected by ARM back to the installation of the 
instrument in July 1997. Please see the current metadata for correct information.  These 
changes do not affect data values or quality.	

The changes are summarized below:
1) Update of "sensor location" information
2) Addition of installation dates for the systems
3) Correction of soil type
4) Correction of soil moisture units (from "by volume" to "gravimetric")

SGP/EBBR/E18 - Sensible and Latent Heat Fluxes and Net Radiation Incorrect

The net radiometer dome was cracked and water had gotten in, resulting in incorrect net 
radiation measurements and therefore incorrect sensible and latent heat flux measurements.

• latent heat flux(e)
• specific humidity(q)
• corrected sensible heat flux(h)
