TWP/SMET/C1 - Periodic spikes in temperature and water vapor pressure
DataStreams:twpsmet60sC1.a1, twpsmet60sC1.b1
Description:
Beginning on 980212 (day #43) spikes began to occur in the surface
temperature and water vapor pressure.  These spikes occur approximately
once per hour (the spacing is very regular but occasionally an hour
is skipped).  In the one-minute averaged data, the temperature spike
lasts for only one minute and dips approximately 4-5 C below the actual
temperature.  The one-minute standard deviation is more dramatic, rising
from about 0.1 to about 35.  The one minute temperature minimum is the
most easily identifiable, each hour when the spike occurs, the minimum
is -245.84.  The vapor pressure mean jumps from about 30 to over 50 and
the standard deviation jumps from less than 1 to more than 200.  This
problem was fixed by the RESET team on 980501.
