Subject: | SGP/EBBR/E13 - Wind Direction Dependency of Surface Fluxes and General Data Quality Information |
DataStreams: | sgp30ebbrE13.b1
|
Description: | Beginning in FY2006, Data Quality Reports are not written for missing
data or for situations when qc flags clearly show that the data is
incorrect (this is true for most of the conditions listed below).
DQRs are written for periods when data is incorrect, when the situation
is not represented by qc flags in the data, and it's not obvious that
the data should have been flagged as incorrect.
The EBBR data is only useful for particular wind directions at each
Extended Facility. Please use the following resources to help in
interpreting the EBBR data.
1) qc flags in the EBBR data.
2) Instrument Mentor Monthly Summaries (IMMS) at http://www.db.arm.gov/IMMS/
3) SGP EF Surface Conditions Observations (EFSCO) at
http://198.124.96.210:591/sfc_cond1/default.htm
4) Surface fluxes are valid only for the following wind directions
(in degrees):
0-52, 142-194, 328-360
Note that there are wind directions at most sites for which the fetch
is insufficient and therefore EBBR data is invalid. Appropriate
fetch was determined from a 1/40 measurement height to fetch ratio,
resulting in a required minimum fetch of 120 m. Particular attention
should be paid to the limited valid wind directions for the Central
Facility EBBR. The surface vegetation type for the EBBRs is grazed
or ungrazed grassland (refer to the EFSCO for state).
5) Some conditions that commonly cause the EBBR primary measurements to
be incorrect or missing follow:
a) Sensible and latent heat fluxes are not accurate during times when
the Automatic Exchange Mechanism (AEM) is not functioning properly.
The AEM switches the gradient measuring instrumentation between the
top and bottom positions every 15 minutes; this reduces the effects of
instrument offsets. Sometimes the AEM does not reach it's full extent
of travel, resulting in the home signal being zero.
b) Sensible and latent heat fluxes are sometimes incorrect when surface
soil heat flow is out of range, as seen in the average soil heat flux
(ave_shf).
c) Very light winds may be seen at nights for brief periods. Wind
direction flops around a lot during low wind conditions (< 1.5 m/s)
and is often unreliable during those periods.
d) Missing data periods occur at times; this is usually a site data
system collection/communication problem; it can also occur during
replacement of the system with a newly calibrated unit. Missing data
is sometimes filled in later from manual or automatic re-collection of
the data. |
