Colombo, Sri Lanka Radiosonde L3.0 Data (ESC Format)


This dataset includes 258 high vertical resolution soundings from Colombo, Sri Lanka (WMO 43466) collected during the DYNAMO field campaign for 2011-12. Soundings were typically released four times daily (00, 06, 12 and 18 UTC) from 30 September 2011 to 6 December 2011. From 7-28 December soundings were released at most once per day at 12 UTC. The station utilized Meisei RS-06G radiosondes. These soundings were provided by JAMSTEC.
