Total CO2 absorption (ton) 20 years in Valladolid City
<p>Urban vegetation plays a vital role in offsetting atmospheric CO<sub>2</sub> by acting as a sink and storing carbon. Carbon sinks can be at the city or urban regional level, with urban green areas having local importance as carbon sinks. However, urban parks can also function as carbon sources due to their management and use producing more CO<sub>2</sub> emissions than their carbon sequestration capacity.</p>

CO2 absorption coefficients (ABSCO) tables for the 4700 to 5100 cm-1 region using Voigt profile accounting for the line-mixing
<p>The attached files include the calculated absorption coefficient (in cm-1) for the 4700 to 5100 wavenumber region when using the Voigt profile accounting for the line-mixing parameter. The structure of the tables is as follows:</p> <p>Col 1- Wavenumber (in cm-1)</p> <p>Col 2- Absorption coefficient using the Voigt profile</p> <p>Col 3- Absorption coefficient using the Voigt profile including the first-order line-mixing</p> <p>Col 4- Absorption coefficient using the Voigt profile including the full line-mixing</p> <p>The JSON files contain the calculation conditions such as pressure, temperature, and mixing ratios of CO2 with a unique ID referring to the specific table.</p> <p>We note that for the Q branch lines and denser regions, the use of the first-order line-mixing is not effective in obtaining the absorption coefficient and the use of full line-mixing is recommended.</p> <p>For more information on how the calculation is performed, see ref. [JQSRT 151, 88 (2015)].</p>

Absorption and Fluorescence spectra of Rhodamine 6G
<p>These data are fluorescence and absorption spectra of Rhodamine 6G. The fluorescence data have some undesirable spikes due to room lights. The absorption data are taken at various concentrations, using a single-monochromator spectrophotometer. The best way to treat them is to stitch the data together depending on which concentration best uses the dynamic range of the detector. The included python script does exactly that. Note that there are slight systematic biases for the largest absorption (underestimate of cross-section due to unwanted multiply scattered fluorescence) and lowest (weak dimerisation of Rhodamine at high concentration).</p> <p>This data is suitable for use in simulations of photon thermalisation, condensation and lasing. It was used by https://doi.org/10.1103/PhysRevA.93.013829 .</p>

<p>Notre étude a porté sur les propriétés d'émission de la curcumine dans les six solvants suivants : l'éthanol, l'acétonitrile, le DMSO, le diéthyléther, le toluène et le cyclohexane. </p> <p>Nous avons réalisé les spectres d'absorption puis d'excitation et d'émission à l'aide d'un fluorimètre de ces six solutions. On a alors pu observer que les propriétés du solvant (polarité et proticité) influent sur l'allure des spectres. </p>

Absorption and Emission Spectral Data of Room-temperature Rhodamine 6G Dye Solution and some typical Dye Microcavity parameters
<p>The repository contains spectral absorption and emission data [absorption cross section and Einstein coefficients] of rhodamine 6G dye solved in ethylene glycol at room temperature over the visible spectral range from 400.25nm to 619.85nm. In addition, typical values for the cavity loss rate are given for the same wavelength range. The data can be used e.g. for studies of two-dimensional thermalized photon gases and Bose-Einstein condensates of photons inside dye-filled optical microcavities.</p> <p><strong>Methodology</strong></p> <p>The absorption data has been obtained by white-light absorption spectroscopy of dye solutions with increasing concentration {0.01,0.1,1} mMol/Litre. The combined spectra have been calibrated with the rhodamine absorption cross section at 532nm wavelength, which we have independently determined in transmission measurements with a 532nm laser. The absorption cross section in this data repository constitutes a universal material property that is generally valid for rhodamine 6G solved in ethylene glycol at room temperature.</p> <p>The Einstein coefficient for absorption B_12 has been obtained specifically for the volume of the transverse ground mode in an optical microcavity formed by two curved mirrors with radius of curvature R = 1 and cavity length D = 1.5µm; see e.g. Klaers et al., <em>Nature</em> <strong>468</strong>, 545–548 (2010), Schmitt, <em>Phys. B: At. Mol. Opt. Phys.</em> <strong>51</strong>, 173001 (2018) and related work by the authors. For typical dye concentrations near 1mMol/Litre, approximately 10^8 molecules are contained in the ground mode volume. The Einstein coefficient for emission B_21 is deduced from B_12 assuming the Kennard Stepanov relation: B_21/B_12 = Exp[-h*c*(1/lambda - 1/lambda_zpl)/(k_B T)], where lambda_zpl = 545nm denotes the zero-phonon line of rhodamine 6G dye (h: Planck's constant, c: speed of light, lambda: wavelength, k_B: Boltzmann's constant, T: temperature). We have verified that the resulting B_21 spectrum agrees well with reference fluorescence spectra of rhodamine 6G. </p> <p>The spectral cavity loss rate c/(n0*D)*(1-R-A) with refractive index n0 = 1.43 and mirror absorption loss A = 1ppm is deduced from the wavelength-dependent mirror reflectivity R, which we have measured in cavity ring-down measurements at more than 10 wavelengths in the interval between 530nm to 605nm. For this, a tuneable dye laser was resonantly coupled into a 3.3cm-long cavity formed by the corresponding highly-reflecting dielectric mirrors. Note that the reciprocal values of the loss rates give the 1/e lifetime of the photons in the cavity.</p> <p><strong>Data format</strong></p> <p>The file 'data.dat' contains all data sorted by columns: wavelength (in units of nm), absorption cross section (in units of m^2), Einstein coefficients for absorption and emission (both in units of Hz), cavity loss rate (in units of Hz).</p>
