table_name description
asm.ambient_lasilla Table containing the ambient measurements of the ESO seeing monitor (DIMM2) located on a 5m high tower, close to the Schmidt telescope. The seeing is defined as the Full Width Half Maximum of a stellar image observed with a perfect large telescope, at 500nm wavelength and at zenith. It is measured over periods of a few minutes all night long. Time coverage: January 1994 onwards. More info at: https://archive.eso.org/wdb/help/eso/ambient_lasilla.html#ambient
asm.dimm_paranal Table containing the ambient measurements of the Differential Image Motion Monitor (DIMM) channel of the MASS-DIMM instrument. DIMM operates in an extended range of atmospheric conditions which overlap science operation. It provides, along with other measurements, the Paranal reference seeing. Time coverage: 2016-APR-04 12:00:00 UTC onwards. More info at: http://archive.eso.org/wdb/help/eso/ambient_paranal.html#dimm_2016
asm.historical_ambient_paranal Table containing the ambient measurements of the ESO seeing monitor DIMM3 seeing monitor, starting August 1998, and up to the deployment in operations of the new Astronomical Site Monitor (ASM) in April 2016. All seeing values above 2.5 arcsec have been truncated. Time coverage: from 1998-Aug-19 to 2016-Apr-04. More info at: https://archive.eso.org/wdb/help/eso/ambient_paranal.html#dimm_1998
asm.lhatpros_paranal Ambient measurements, since 2014, of the Low Humidity and Temperature Profiling (LHATPRO) microwave radiometers located on Cerro Paranal. Measurements at zenith of: infrared temperature, liquid water path, and precipitable water vapour. Averages over the reported integration time. Three radiometers (identified by their LHATPRO ID: 1, 2, 3) are currently available at different locations named: A, B, C.

asm.lhatpros_paranal_irt Ambient measurements, since 2014, of the Low Humidity and Temperature Profiling (LHATPRO) microwave radiometers located on Cerro Paranal. Measurements at provided coordinates of the infrared temperature. Averages over the reported integrtion time (up to 5 seconds, as of 2020). Three radiometers (identified by their LHATPRO ID: 1, 2, 3) are currently available at different locations named: A, B, C. More info at: http://archive.eso.org/wdb/help/eso/ambient_paranal.html#lhatpro
asm.lhatpros_paranal_profiles Ambient measurements, since 2014, of the Low Humidity and Temperature Profiling (LHATPRO) microwave radiometers located on Cerro Paranal. Atmospheric profiles at provided coordinates and at 39 different altitudes from 0m to 10,000m over the VLT platform, of absolute and relative humidity, and infrared temperature. Averages over the reported integration time (typically 60 seconds). More info at: http://archive.eso.org/wdb/help/eso/ambient_paranal.html#lhatpro
asm.mass_paranal Table containing the ambient measurements of the Multi-Aperture Scintillation Sensor located in Paranal. Included measurements like; vertical profile of the turbulence Cn2(h) (6 layers), Isoplanatic angle, Coherence time, etc. More info at: http://archive.eso.org/wdb/help/eso/ambient_paranal.html#mass
asm.meteo_apex Table containing the ambient measurements of the APEX weather station, which is located on a free-standing 6m high tower located about 50m West of the APEX telescope. The sensors are from Vaisala, except the temperature sensor, which is from Stego. The APEX radiometer was built by Radiometer Physics GmbH (MeckenHeim, Germany). Time coverage: January 1st 2006 onwards. More info at: https://archive.eso.org/wdb/help/eso/meteo_apex.html
asm.meteo_lasilla Table containing the ambient measurements of the Vaisala METEOrological station, which was installed at La Silla in February 1985. It includes, on a 30 m high mast, a number of sensors. The following measurements are provided: Wind speed and direction, Temperature, Humidity at different levels. Time coverage: January 1st 1994 onwards. More info at: http://archive.eso.org/wdb/help/eso/ambient_lasilla.html#meteo
asm.meteo_paranal Table containing the ambient measurements of the Vaisala METEOrological station, which was installed in Paranal in October 1984 and upgraded in June 1998. It includes, on a 30 m high mast, a number of sensors. The following measurements are provided: Wind speed and direction, Temperature, Humidity, Particle Count at different levels. Time coverage: August 1998 onwards. More info at: http://archive.eso.org/wdb/help/eso/ambient_paranal.html#meteo
asm.slodar_paranal Table containing the ambient measurements of the SLOpe Detection And Ranging (SLODAR). SLODAR is optimised to measure the vertical profile of the surface layer of turbulence, in the first 100m above the site. The data is relevant to modelling and understanding the imaging performance of the VLT, both with and without adaptive optical correction. Time coverage: 2016-APR-04 12:00:00 UTC onwards.
