Description: | On August 26, 1995 at approximately 0345 GMT the gears on the lower sprocket
shaft of the AEM appear to have been damaged, causing the AEM to stop
exchanging. The home signal values then remained at around -0.5 for both
home_15 and Home_30. On August 29 site operations personnel removed the fuse
(to prevent exchange) with the left aspirator in the down position. The AEM
will remain in this condition until a replacement is available.
Therefore, the calculations of Bowen ratio, latent heat flux, and sensible heat
flux are incorrect for all times after August 26, 1995 at 0345 GMT. The data
fields listed below are incorrect after this time:
5 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top, hum_bot,
vp_top, vp_bot
30 minute: tair_top, tair_bot, thum_top, thum_bot, hum_top,
hum_bot, vp_top, vp_bot, Bowen, e, h.
It is not possible to reliably calculate the Bowen ratio, e, and h using the
15 minute data. |
