- Data evaluated:
BALTRAD 2019-09-24 - 2019-10-31 /CN19.
BALTRAD 2012 - 2017. Single days in multiple years in April/May and August/September. /CN22.
-
BALTRAD 2012-2017: Large data gaps in 2013-2014, and no data in 2017. Overall data looks ok, bird signals are generally weak as we have seen before, and gets weaker the more north. Almost none have speed and direction indicated. In some cases biological signals are filtered out by the default sd_vvp (2), and there are some cases of rain contamination.
Settings checked:
dealiased_perc: Ok, almost always 100 but sometimes around 95-97% for certain radars certain days.
wavelength: Ok, 5.35
dualPol_filtering_perc: Ok, 0.00
singlePol_filtering_peerc: Ok, 100.00
n: Very variable, between 14 and 96
/CN22 -
Many radars have changed codes. /PD20
-
Overall good, but many stations have a limited height range available, around 1200 m above ground for many stations (1500-1800 above sea level). /CN19
0: not available, 1: available, 2: poor quality, 3: good quality

- BALTRAD 2012-2017: Birds present, rain contamination also present. /CN22
- BALTRAD 2019: Height cut off at approx 1500m. Only data for October evaluated. /CN19
- BALTRAD 2012-2017: Note that code then was sevil: Birds present, default sd_vvp seems too high. /CN22
- BALTRAD 2019: Height cut off at approx 1500m. /CN19
- BALTRAD 2012-2017: Birds present, very weak signals. Rain contamination occurs. /CN22
