Precipitable Water Vapor Tables from ECMWF ERA5 Re-Analysis for SOFIA FIFI-LS Flights
No full textSOFIA Precipitable Water Vapor (PWV) Products for all flights with FIFI-LS between the year 2014 and 2022.
Each FITS file contains a HDU "DATA", which is a binary table extension with columns for
Precipitable Water Vapor (PWV), Longitude, Latitude and Atmospheric Pressure
as a function of in-flight time. The source for positional data
is the primary GPS sensor of SOFIA (see POSSRC keyword).
PWV values were derived from the ERA5 Re-Analysis from ECMWF
(Hersbach, H., 2020, DOI:10.1002/qj.3803).
Note: For use of PWV values for atmospheric transmission correction
by the instrument pipeline software, a specific instrument dependent
conversion must be performed. Please refer to the respective
documentation in the SOFIA Redux module for FIFI-LS for further details.
Derivation of the ECMWF PWV values and specific instrument
correlations for FIFI-LS are explained in detail in, e.g.,
Fischer et al., 2021, DOI:10.1088/1538-3873/abf1ca and
Iserlohe et al., 2021, DOI:10.1088/1538-3873/abef76.
Percentiles, Pk, for given geographical position and flight altitude
of SOFIA and season of the observations are derived
from a 10 year statistics presented in
Iserlohe et al., 2022, DOI:10.1088/1538-3873/ac82c5.
Pk means that there is a k% probability of observing a PWV value less than Pk in flight.
The FITS files also contain some water vapor maps of the region of the flight path for data validation purposes.

The Cathedral of St Alexander Nevski in Sofia.
No full textPreviously in the University eprints HAIRST pilot service at http://eprints.st-andrews.ac.uk/archive/00000393/Article 4 of 6 in an issue devoted to the visual culture of South Eastern EuropeBuilt to celebrate the liberation of Bulgaria from centuries of Ottoman domination, the Cathedral of St. Alexander Nevski in Sofia has aroused only scant interest among art historians both inside and outside the country. In recent years, the general disinterest surrounding this monument can be ascribed to the political climate in Bulgaria after the Second World War; for almost half a century the militant atheism of the Communist regime stifled the religious feelings of the Bulgarian people, forcing believers underground. Consequently, under pressure from the regime, religious works of art and places of worship fell into neglect.
In view of this void, the aim of my research was to document as completely as possible all the various aspects of the Cathedral of St. Alexander Nevski. I then traced the history of Bulgaria, starting from the Ottoman conquest and focusing particularly on the period of the Bulgarian Renaissance, which led the country, with the help of Russia, to freedom from the Turkish Empire and then to independence. I hope that this study will shed a glimmer of light on this splendid building and help to stimulate interest in Bulgaria's artistic heritage.Postprin
Atmospheric transmission models for FIFI-LS: altitude 43kft, 39deg O3
No full textThis dataset contains atmospheric transmission models calculated by a modified version of ATRAN ("SDC ATRAN"). They are to be used as the default models for FIFI-LS data reduction with SOFIA Redux
The models are generated from a modified "SDC ATRAN" model based on Steve Lord's ATRAN. The most significant modification is a correction of 17O16O isotopologue abundance coefficients.
The models are stored in FITS binary table format with the columns "wavelength" and "transmission". All models of the same altitude (and same wavelength range) have the same number of wavelength elements.
File naming convention:
atran_sdc_xxK_yydeg_zzpwv_39deg_2nlayer_40-300mum_bt.fits
where xx is the flight altitude in kft, yy is the zenith angle in degree, and zz the
precipitable water vapor value in micron.
This dataset contains models calculated for a 2 layer atmospheric model with an ozone profile identified by "39deg".</p

Premessa a Per d’Arco Silvio Avalle, «Le forme del canto». Interventi di Lino Leonardi, Pietro G. Beltrami, Maria Sofia Lannutti, Arnaldo Soldani
No full textThis collection of essays on medieval poetic metres, edited by Maria Sofia Lannutti following the arrangement conceived by its author, confirms the importance of d'Arco Silvio Avalle's metrical studies. Key issues are the relationship between metrical structure and music in the texts dating back to the origin of romance literatures, the multi-perspective complexity of the approach, and the exemplarity of the methodology used. © 2019 Societa Editrice il Mulino.
