GRUMETS has own equipment to develop their research:
- Servers with processing capacity
- Meteosat Second Generation Antenna (MSG)
- Field Radiometers
- Meterological stations
Both at CREAF and at the Department of Geography, the group has wide processing capacity with various computers for massive parallel calculations with MiraMon and other specialized programs, as well as for experimentation and applications in geoservices. Specifically, we have 31 servers with 63 processors and 302 cores, with a total of 664 GB of RAM.
Due to major improvements in the Meteosat Second Generation(MSG), operating since 2004 and with a minimum continuity until 2015, from CREAF we believed that the current MSG resolutions could help in various fields of interest including radiometric correction of other sensors, Vegetation index calculations, active fires, aerosols studies and climate change, among others. So, with a low budget was installed and launched, in 2007, a receiving station, taking advantage of the free data for research groups. Every 15 minutes we receive the MSG images that are imported into MiraMon software format, for a further internal CREAF-UAB staff use. Besides MSG images, we can also receive images from other meteorological satellites (Metop, GOES, etc.) Processed products as well.

It has been acquired recently, by the Department of Geography at the UAB, two field radiometers with detectors in the range of visible, near infrared and shortwave infrared, divided into ranges (200-1100 nm) and (900 -2500 nm).
USB2000+ Miniature Fiber Optic Spectrometer: consists of an analog to digital converter of 2MHz, programmable electronics, a 2048 CCD detector elements, and a USB 2.0 Hi-Speed. Provides a resolution of 0.35 nm (FWHM).
NIRQuest256-2.5 Near-Infrared Spectrometer: comprises a linear-type detector 256 pixels and an optical resolution of 9.5 nm (FWHM).
We have a meteorological station in Vallcebre, in a meadow area, equipped with the following instrumentation:
-Air temperature sensor.
-Two ST sensors.
-Incident and reflected solar radiation (albedo can be calculated).
-Skye Sensor R + G+ B + Irp configuration similar to Landsat-5-7-LDCM and some bands of MODIS.
-Soil Moisture (sensor belonging to IDAEA).
-Flow soil heat sensors (sensors belonging to IDAEA).
-Wind speed and direction.
These stations provide a validation area for radiometric correction and satellite images, and in the same time, allow the development of moisture indices joining solar and thermal bands.
