Mean Wind of Sonics |
Error in Database. Vector mean and scalar mean of all Sonic anemometers at BSPA, BSPR, ALLS, BKLI and GRNZ were attributed in a wrong way in the database. Instead of vector mean, the download process extracted scalar mean wind speed of the same instrument and the other way round! Now, this problem has been fixed.

Turbulence |
Turbulent length scales determined from autocorrelation and crosscorrelation functions are available in the database.

general |
Fixed
a technical problem which made it impossible to download time series
with time intervals >= 60 min between two measurements. Now,
60min data can be downloaded.

Corrected
energy and mass flux densities added to the database. The new
parameters are:
- Sensible
Heat Flux Density (corrected)
- Latent
Heat Flux Density (corrected)
- Soil Heat
Flux Density (corrected)
- CO2 Mass
Flux Density (corrected)
Information
on applied corrections and data processing can be found in the Sonic
Data Processing Documentation.

Automatically
processed data from the Wind Profiler at
"Basel-Spalenring" added to the database (level B of
low-mode) to the database. 2001-2002. |

Error
in calibration of temperature/humidity (psychrometer-calibrations) at
Basel-Sperrstrasse at level 21.50m (BSPRDTA4,BSPRDTA2) and Level 31.20m
(BSPRDTA6) was leading to offset of 0.2 to 0.3K. Calibration should
be ok now. |

BSPR |
CO2
and H2O -Fluxes |
Error
in hardware (delay time) leads to wrong offset between LICOR
7500 and Sonic. Problem fixed. Refer to "Short
Note on LICOR 7500 Lag Correction" for details. |

BSPA |
Radiation |
Error
in calibration of long-wave downward radiation at Basel-Spalenring
fixed (BSPRLDA1). See also the Radiation-Report on
detailed information of radiation instruments
and calibrations during BUBBLE. |

Traffic
Counter |
Error
in timing information of traffic counter data fixed (BSPRTRT1). Timing should be ok now. |

Sodar
data of "Grenzach" (Uni Basel) and "St.Louis (Uni
Freiburg) added. See also overview plots
