Tartu Acnometric Staon was established in 1950, it was also the beginning of regular mea- surements of global and direct irradiance. The measurements of diffuse irradiance were added in 1954, reflected irradiance in 1955. Tartu-Tõravere Meteorological Staon (since 1965) Φ = 58°16´ λ = 26°28´ h = 70 m Radiaon measurements were moved to Tõravere, 20 km from Tartu, in 1965. The staon became a BSRN candidate in 1993, since 1999 it has opera- ted as a BSRN staon. Data from period 19.01.1999 - 31.05.2018 are submied to BSRN arhcive.

Tartu Actinometric Station (1950-1965) Φ = 58°21´ λ = 26°41´ h = 76 m The longest time series of radiation measurements in Estonia can be obtained from Tartu-Tõravere. Tartu Actinometric Station was established in 1950, it was also the beginning of regular mea-surements of global and direct irradiance. The measurements of diffuse irradiance were added in 1954, reflected irradiance in 1955.

Tartu-Tõravere Meteorological Station (since 1965) Φ = 58°16´ λ = 26°28´ h = 70 m Radiation measurements were moved to Tõravere, 20 km from Tartu, in 1965. The station became a BSRN candidate in 1993, since 1999 it has opera-ted as a BSRN station. Data from period 19.01.1999 - 31.05.2018 are submitted to BSRN arhcive.

Tartu-Tõravere

Radiation sensors: 1. direct irradiance (PMO6 absolute radiometer, pyrheliometers

AT-50, NIP, CHP1, spectral radiometer PFR) 2. global, diffuse and reflected irradiance (pyranometers CM-21

with ventilation unit) 3. broadband UV, UVB narrowband, UVE irradiance (CUV3,

CUVB1, UVS-E-T) 4. photosynthetically active irradiance, global and direct (LI-COR

LI-190SA) 5. downward longwave irradiance (pyrgeometer CGR4 with

CVF4 ventilation) 6. upward longwave irradiance (Eppley PIR) 7. sun tracker 2AP 8. total ozone measurements (MICROTOPS II)

New sensors mounted during summer 2018: 1. global, diffuse and reflected irradiance (pyranometers SMP-

21 with CVF4 ventilation unit) 3. broadband UV, UVB (CUV5, UVS-B-T) All sensors will be connected with new data acquisition system.
