Subject: | SGP/EBBR/E8 - Water in Net Radiometer |
DataStreams: | sgp30ebbrE8.b1, sgp15ebbrE8.b1, sgp5ebbrE8.b1 |
Description: | At some time previous to October 21, 1994, the top hemisphere of the net radiometer of the EBBR at E8 was pierced, probably by migrating birds. A DQR was issued by me a couple of weeks ago indicating other extended facilities at which this has happened. Net radiometer data was correct until October 21 at sometime between 0230 and 0300 GMT, when rain began to enter the radiometer; the effect can be easily seen in the data. Collection of 3/4 inch of water in the bottom hemisphere was not the only consequence of the situation. Unlike other net radiometers that have had this experience, this one produced incorrect data during daylight hours as well as during nightime hours until the water was removed, the sensor dried, and the hemispheres were replaced on November 2, 1994. During the period listed above, the following data are incorrect and cannot be recalculated: 5 minute: q 15 minute: mv_q 30 minute: q, h, e Science Team members or others using the data should recognize that the flux data is not correct for this fairly lengthy time period. |
