| Zusammenfassung | We describe an instrument dedicated to the measurement of the Top Of Atmosphere (TOA) solar spectral irradiance (SSI) in the near infrared (NIR) between 600 nm and 2300 nm at a 10 nm resolution. Ground based measurements are performed through atmospheric NIR windows and the TOA SSI values extrapolated using the Bouguer-Langley technique. The interest in this spectral range comes from its main role in the Earth’s radiative budget as well as for the validation of models used in solar physics. Moreover, some differences were observed between space instruments measuring in the NIR: In the 1.6 μm region, SCIAMACHY shows a deviation of up to 10% to the reference SOLSPEC(ATLAS3). Our measuring system named IRSPERAD has been designed by Bentham (UK) and radiometrically characterized and absolute calibrated against a blackbody at the Belgian Institute for Space Aeronomy and at the Physikalisch-Technische Bundesanstalt (Germany), respectively. A four month measurement campaign was carried out at the Izanna Atmospheric Observatory (Canary Islands, 2367 m a.s.l.). A set of top quality solar measurements was processed to obtain the TOA SSI in the referred NIR windows. We obtained an average standard uncertainty of 1% for 0.8 μm < λ < 2.3 μm. At 1.6 μm, corresponding to the minimum opacity of the solar photosphere, we obtained an irradiance of 234.31 ± 1.29 mWm -2nm -1 . Between 1.6 μm and 2.3 μm, our measurements show a disagreement varying from 6% to 8% relative to ATLAS3, not explained by the declared standard uncertainties of both experiments. |
