Subject: | SGP/EBBR - Incorrect Units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in 30EBBR |
DataStreams: | sgp30ebbrE12.b1 |
Description: | The units for Soil Heat Capacity (cs1, cs2, cs3, cs4, cs5) in the EBBR 30 minute netcdf header have been incorrect from the beginning of processing the data into netcdf files. The correct units are MJ/m^3/C. This does not affect the data quality. (NOTE: The actual begin date of some of these data streams is as early as 7/4/93. This DQR applies to all 30m EBBR data.) |

Subject: | SGP/EBBR/E12 - Wind Direction Sensor Malfunctions |
DataStreams: | sgp30ebbrE12.b1 |
Description: | For much of the period above, a malfunction in the E12 EBBR wind direction sensor (insect larvae shorting out the circuit board) caused incorrect values for 5 minute res_ws, wind_d, and sigma_wd, 15 minute mv_wind_d, and 30 minute res_ws, wind_d, and sigma_wd. Wind direction normally indicated north (near 0 or 360 degrees); there were some times during the period when wind directions looked good, but the lack of variation in direction and sigma implies that the data is suspect. Therefore, it would be wise to flag all of the values listed above during the entire time period as incorrect. The wind direction sensor (S/N 3081) was replaced with S/N 3042 at 1515 GMT on June 8, 1997. |
