    Sun Photometer Data (AOD) 2020 from Zeppelin Station, Ny-Ålesund, Svalbard (AWIPEV) (2021)

    Details
    Publication Date: 2024-04-20
    Description: Aerosol optical depth (AOD) is measured by a sun photometer, type SP1a by Dr. Schulz & Partner GmbH in 17 wavelengths between λ = 369nm to 1023nm with a field of view of 1° × 1° and a time resolution of 1 minute. In winter 2012/13 a new sun photometer was installed and just 10 of 17 wavelengths remained in the same wavelength range. With the nine out of ten wavelengths optical parameters like the AOD are computed. The one, which is devoted to water vapor is omitted. The instrument is calibrated regularly in pristine conditions at Izaña, Tenerife, via Langley method. A cloud screening based on short scale fluctuations of the AOD is used. The uncertainty for the AOD is generally said to be around 0.01. However, this is the maximum error of the instrument because the fluctuations are much smaller by comparing data minute by minute under low or constant aerosol conditions. The number of individual measurements differs between a few hundreds, especially in March and September, to up to 12,000 in early summer. No trend in each month can be seen comparing the amount of cloud-free measurements over the years. Only an annual cycle due to polar day and night is included in the data. Due to the instrument data is only available in clear sky conditions. In this regard the data should represent the real aerosol conditions. Only aerosols that are advected and processed within clouds or hygroscopic growth cannot be measured by this instrument. In this data set AOD, Angstrom-Exponent and modified Angstrom-Exponent (Graßl, Ritter 2019, Remote Sensing, https://doi.org/10.3390/rs11111362) are given for the sun photometer at Zeppelin Station, operated by AWIPEV, for the time 28. July 2020 until 30. September 2020. The variables are in netcdf format for each measurement day. The used instrument for the measurement period was SP1A31.

    Notes: Silylierte Diamine gehen mit Phosgen bereits in der Kälte augenblicklich unter Ringschluß in die entsprechenden silylierten Heterocyclen über. So werden aus N.N′-Bis-trimethylsilyl-trimethylendiamin und -tetramethylendiamin N.N′-Bis-trimethylsilyl-trimethylen- bzw. -tetramethylen-harnstoff gewonnen, die durch Hydrolyse Trimethylen- bzw. Tetramethylen-harnstoff liefern. - Diamine, wie 4.5-Diamino-uracil, die mit Phosgen nicht reagieren, werden durch vorherige Silylierung reaktionsfähig. Tetrakis-trimethylsilyl-diamino-uracil wird mit Phosgen in 80 proz. Ausbeute in Tetrakis trimethylsilyl harnsäure übergeführt, die quantitativ zu Harnsäure hydrolysiert wird. Selbst mit Kohlendioxyd konnte das silylierte Diamino-uracil zu Harnsäure umgesetzt werden.
