Global solar radiation

It is the energy directly radiated by the sun and reflected by the surrounding elements.

Rock temperature

Pera is able to measure the surface temperature of the rock and inside it, thanks to sensors placed at different depths.
Unlike the air temperature, on sunny days, the temperature of the rock can rise by many degrees above the daily average, because the rock heats up much more easily than the air.

Attention! The temperatures displayed are those measured on the surface and inside the rock, not those of the air!
On sunny days, it is common for the temperature of the rock to reach high temperatures, due to the different characteristics of heat conduction.

Surface wetting

Pera determines the surface wetting by measuring the conductivity of the water.
In the presence of ice or snow, Pera may be dry because ice is not a good conductor.

Internal rock temperature at -10cm

Pera has temperature sensors placed inside the rock, at different depths.

4,32 °C

Internal rock temperature at -30cm

Pera has temperature sensors placed inside the rock, at different depths.

6,05 °C

Internal rock temperature at -50cm

Pera has temperature sensors placed inside the rock, at different depths.

6,23 °C

Surface wetting

Pera determines the surface wetting by measuring the conductivity of the water.
In the presence of ice or snow, Pera may be dry because ice is not a good conductor.

Humid

Hours of sunlight

These are the hours of light measured yesterday.
For Pera this figure also represents the time in which he was able to recharge thanks to its small solar panels.

14,3 hours

Current energy

Pera has small solar panels to recharge. This is its remaining energy now.
