Collections

Collections allows the user to search in subsets of the existing catalogue. The collections are primarily data management projects that have been incorporated in the ADC catalogue. The collections currently served through ADC include (datasets may belong to multiple data collections):

ADC is the full collection of this service CC is the CryoClim collection

In order to search a specific data collection select that collection. If no data collection is selected all collections are searched.

GCW is the collection for the WMO Global Cryosphere Watch
NMAP is the NORMAP e-infrastructure collection
NSDN is the data collection for the Norwegian Scientific Data Network
SIOS is the data collection for the Svalbard Integrated Arctic Earth Observing System
YOPP is the data collection used to serve the Year of Polar Prediction

Status of collections

Some data collections are currently in the process of being added to the system. This includes:

DOKI is the data collection for the Norwegian contributions to the International Polar Year.
- This is currently being cleaned for reimplementation.
DAMOC is the data collection for the EU FP6 project DAMOCLES
- This is currently being cleaned for reimplementation.
ACCESS is the data collection for the EU FP7 project ACCESS
- This is currently being cleaned for reimplementation.
APPL is the data collection for the EU H2020 project APPLICATE
AP is the data collection for the EU H2020 project Arctic Passion
- This is in the process of being populated.

Abstract:
This data set includes vertical profiles of wind speed (FF), wind direction (DD), fit deviation (FD) and the backscatter confident (BB) measured by a ship born wind lidar. The definition of the fit deviation, the main processing of the lidar data and an evaluation of the measurements is described in Zentek et al. (2018; doi:10.5194/amt-11-5781-2018 ). For this data set winds were computed every 50 m up to 1000 m and the data is averaged over time. The averaging time is one hour (+-30min around each full hour) and missing values are removed. A weighted arithmetic mean was used for the u- and v-component as well as for the fit deviation with the weights "1/fit deviation". The backscatter coefficient was averaged without weights. As backscatter was always measured, hours were included even if no wind could be computed due to atmospheric conditions but hours with no reliable data were excluded (e.g. the lidar was turned off; the ship was rocking to hard; etc.). Further detailed information for this measurement campaign: number of rays per VAD [6-8], averaging time [3-8 sec], chosen SNR threshold [-19 dB]. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.902805"! ** The measurements were performed during the Polarstern cruise PS109 funded by the Alfred Wegener Institute under Polarstern grants AWI_PS109_12. The research was funded by the Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung–BMBF) as part of the project CATS ("The Changing Arctic Transpolar System") under grant 03F0776D.
