Lunar Photometry Campaign and Workshop at Izaña 2017


Campaign: June 1st – 17th, 2017
Workshop: June 7th – 8th, 2017

The Lunar Photometry Intercomparation Campaign is organized by Izaña Atmospheric Research Center (IARC) of the Spanish Meteorological Agency (AEMET) and the Atmospheric Optics Group of Valladolid University (GOA-UVa).

This campaign will take place at the Izaña Atmospheric Observatory on June 1st – 17th, 2017. The objective of the campaign is to compare the nighttime aerosol optical depth (AOD) of the participating instruments by using light from moon or stars, and to evaluate the uncertainty from the different methodologies. A parallel Workshop will take place at Izaña on June 7th and 8th, focused on the analysis of lunar photometry measures.

Attendance at the campaign is by invitation only, but any researcher active in this area is welcome to apply to attend the meeting via email. If you are interested to join the campaign, please contact the organizers Carlos Toledano ( or Emilio Cuevas ( For shipment and operational matters please contact Natalia Prats (

All participants are kindly requested to confirm their participation by filling in the on-line form.

The Izaña Atmospheric Observatory is at the island of Tenerife at 28º18’N, 16º29’W, 2367 m a.s.l. The Observatory is located on the top of a mountain plateau in a pre-national park area (Teide National Park) that is environmentally protected by the “Sky Law”. The Observatory is normally above a temperature inversion layer, generally well established over the island, and so free of local anthropoge­nic influences.

For information on current weather conditions you can access the Observatory website and the webcams installed at Izaña. There is also an automatic weather forecast as well as warnings of adverse meteorological conditions. For the automatic weather forecast user and password is required.

If you have any questions about the campaign/workshop, please contact campaign staff for assistance.

The Canary Islands are not part of European Community territory for the purposes of VAT (see Taxation and Customs Union). We don’t have VAT and we apply our local tax IGIC. For this reason, to move goods it is always necessary to carry out a customs clearance, both for exportation and for importation, even for European shipments.

There are two options for the custom clearance when import instruments to Izaña Observatory:


ATA Carnet, issued by chambers of commerce, simplifies Customs procedures for the temporary import/export of goods. Additional information can be found here.

Temporary Importation (for Countries not accepting ATA Carnet)

Import taxes and customs expenses are due when importing goods into the Canary Islands. A pro-forma invoice must be provided to the courier company. There is a tax exemption for the transport of the instrument to Izaña Observatory based on the agreement between Spain and Germany when creates the GAW Station. In addition to the taxes, there are some customs expenses that should be assumed by the sending institution.

Please send a copy of the pro-forma invoice in advance to to prepare the taxes exemption certificate. We’ll also need:

  • the place where the instrument come from
  • the number of boxes, size and weight
  • serial number of the instruments
  • statistical (legal) value of the instrument
  • courier company

It is understood that the sending institution bears all costs of the shipment until the observatory is reached. Please use DDP (Delivered duty paid) as term of payment and delivery to avoid any additional costs that we are not prepared to pay. Please send us the tracking number for verification.

When planning the shipment, keep in mind that customs clearance formalities may require additional transit time.

To stay at the Izaña Atmospheric Observatory it is recommended to rent a car as there is no public transport. Remember that the Observatory is located at an isolated area, and the nearest supermarket is at La Esperanza, about 50 minutes drive away.

At the Izaña Atmospheric Observatory there is a small residence on the 2nd floor, with 6 double rooms. These rooms are reserved during the campaign to those groups operating non-automatic instrumentation. The residence has a small kitchen where you can use a microwave but not really cook. The Observatory has also a kitchen and dining room at ground floor reserved for the observatory staff. Please, where possible, use the 2nd floor kitchen.

You can also book a room at the IAC (Astrophysics Observatory) which is only 2km away from the Izaña Atmospheric Observatory. The Astrophysics Observatory, can also provide meals (lunch and dinner). Both services requires online registration. If you choose to book in the IAC, please let us know and fill out the online form with your personal data as well as the following options:

  • Proyecto IAC: (000000) Privado. No IAC
  • Relación IAC / IAC relation: LUNAR campaign at AEMET
  • Telescopio de trabajo / Working Telescope: Administración (By default)

Please remember that reservations of menu at the IAC restaurant must always be made before 10:30 for lunch and before 15:00 for dinner. You can find here more info about services at the IAC residence and restaurant.

This campaign is supported by the European project ACTRIS-2 (GA654109), part of the European Union’s Horizon 2020 research and innovation programme, and the Spanish project Polarmoon (CTM2015-66742-R), founded by the Spanish Ministry of Economy, Industry and Competitiveness (MINECO) and the European Regional Development Fund (ERDF).
