European Centre for Medium-Range Weather Forecasts Operational Analysis data set

Entry ID: BADC_ECMWF_OPERAT_ANALYSES

[ Update this Record ]

Summary

Abstract: Operational analyses from the European Centre for Medium-Range Weather
Centre (ECMWF) are available through BADC for the period since March
1994. The data is updated monthly, two to three weeks after the end of
the month, e.g data for June becomes available soon after mid
July. Vorticity, divergence, temperature, surface pressure and
vertical velocity data in T106 spectral form plus specific ...

Quality Data collected by the LIDAR system include the density, temperature, wind velocity and aerosol loading as a function of altitude from near the ground (typically, above about 15 km altitude) to the upper mesosphere. The spatial and temporal resolutions of the data depend on the operating mode of the lidar, time of day, and local meteorological conditions.

Taken from the ... 2008-2009 Progress Report:
Field work:
All fieldwork was undertaken at Davis. During the review period, the lidar was operated as often as practicable during suitable weather conditions, with approximately 1200 hours of data collected between June 2008 and April 2009. The fieldwork milestones were; (1) July-October 2008 - special high resolution observations of Polar Stratospheric Clouds, coordinated with observations of the CALIPSO satellite mission and flights of balloon-borne ozonesondes, (2) November 2008 to February 2009 - special day and night profiling for Polar Mesospheric Clouds in coordination with MST radar operations and AIM satellite overpasses, (3) ongoing - coordination of lidar observations with ozonesonde and special radiosonde flights provided by the Bureau of Meteorology, and Antarctic lidar measurements conducted at Dumont d'Urville (by France) and McMurdo (by Italy). Progress with data collection met expectations.

Laboratory activity/analysis:
Analysis activity, including data checking, was undertaken primarily at AAD Head Office. Additional data checking was performed at Davis and in the case of ozonesonde data, by the Bureau of Meteorology in Melbourne. The progress of this activity has been as expected. The main activities were (1) basic data checking to ensure that the instrument and data collection software was performing as expected, (2) validation of temperature data where possible using in-situ measurements from BoM radiosondes and soundings from satellite missions (Aqua, TIMED, Aura, COSMIC, ACE) and assimilated global data sets (UKMO, NCEP, GEOS4), (3) analysis of backscatter from Polar Stratospheric Clouds (PSC) and Polar Mesospheric Clouds (PMC), and (4) analysis of ozone data from ozonesondes. All of these activities are on-going.

Taken from the 2009-2010 Progress Report:
Field work:
All fieldwork was undertaken at Davis. The lidar was operated by Dr Simon Alexander (2009 wintering Head Office Research Scientist) and Jeff Cumpston (2010 wintering Lidar Scientist), with additional involvement by Dr Andrew Klekociuk (2009/10 summer), Theo' Davis (La Trobe University, 2008/09 and 2009/10 summer) and Roland Stehle (2009 wintering engineer). During the review period, the lidar was operated as often as practicable during suitable weather conditions, with approximately 385 hours of data collected between July 2009 and April 2010. The amount of data collected was lower than recent years.

The fieldwork milestones were; (1) Jul-Oct 2009 - special high resolution observations of the Upper Troposphere- Lower Stratosphere using the Raman technique for temperature profiling, (2) Nov 2009 to Feb 2010 - special day and night profiling for Polar Mesospheric Clouds in coordination with MST radar operations and AIM satellite overpasses, (3) ongoing - coordination of lidar observations with ozonesonde and special radiosonde flights provided by the Bureau of Meteorology, and Antarctic lidar measurements conducted at Dumont d'Urville (by France) and McMurdo (by Italy).

A high power laser was acquired to replace the existing laser to improve operational reliability; the new laser was successfully installed at Davis during the 2009/10 summer.

All of these activities are on-going.
