| Subject: | SGP/VCEIL/B1 - Reprocess: CBH reported in feet but labeled meters |
| DataStreams: | sgpvceil25kB1.a1, sgpvceil25kB1.b1
|
| Description: | The cloud base heights reported in the file are in feet despite being labelled meters.
Reprocessing of this data is highly recommended.
The first affected file is from 2000-11-22 when the ceilometer was brought back on line
following a factory repair. The last affected file is on 2001-12-13 when the new
vceil_ingest version 7.2 was released which applies the proper units conversion from feet to meters. |
| Suggestions: | Simply convert from feet to meters:
Y meters = X feet * (12"/foot) * (2.54 cm/in) * (1 meter/100cm) |
| Measurements: | sgpvceil25kB1.a1: - Vertical visibility(vertical_visibility)
- Lowest cloud base height detected.(lowest_cloud_base_ht)
- Altitude of highest signal(alt_highest_signal)
- -180.0 - +180.0(alt)
- Second lowest cloud base height(second_cbh)
- Third cloud base height(third_cbh)
- Lowest cloud base height detected(first_cbh)
