<p>Data accompanying the publication: High-resolution Soil Moisture Evolution in Hyper-arid Regions: A Comparison of InSAR, SAR, Microwave, Optical, and Data Assimilation Systems in the southern Arabian Peninsula. For filenames starting with T: Exponential fit parameters time0 and mag0 for InSAR coherence data. they are binary files, where fit = a*exp(-b*x); a = -log(mag0); b = 1/time0. timeerr contains the uncertainty of the time0 parameter, and maghigh/maglow contain the high and low uncertainty for the mag0 parameter, respectively. For for each frame or overlap region (T101, T28, T130, T28_T101, T130_T28), there is a vrt file (T..._20180524.time0.vrt), which is the metadata file applicable to all files of the same frame. Files starting with mags_times: Exponential fit parameters for ASCAT/SMAP/GLDAS data. the same parameters (time0, timeerr, mag0, maghigh, maglow) can be found in these matlab structure files. In addition, the .mat files contain the offset parameter and related uncertainty, as well as lat/lon information. </p>

Figure 5 in Arenopsaltria nubivena (Cicadidae: Cicadinae: Cryptotympanini) from the Arid Regions of Central Australia and Southwest Western Australia
Figure 5. Arenopsaltria nubivena, waveform plots of calling songs from 5.6 km west of Windorah, southwest Queensland; (A) general view showing the relatively uniform, continuous buzzing song, but showing two short breaks (marked by hollow arrows); (B) time expanded segment of calling song showing the repeated macrosyllables, each with six dominant syllables, the arrows defining the limits of the individual macrosyllables; (C) higher resolution waveform plot of two macrosyllables, the filled arrow marking the boundary between the macrosyllables. The six dominant syllables (DS) each comprise 5 to 7 high amplitude carrier wave pulses. The time intervals between the dominant and secondary syllables (SS) comprise lower amplitude background pulses, variably frequency modulated; the horizontal arrows define the syllable repetition rates (RR) and the intra-syllable durations between the dominant and secondary syllables. Field recordings, filtered to 1 kHz.

Figure 2 in Arenopsaltria nubivena (Cicadidae: Cicadinae: Cryptotympanini) from the Arid Regions of Central Australia and Southwest Western Australia
Figure 2. New distribution records for Arenopsaltria nubivena. Filled arrows indicate locations of audio recordings. The generalized distribution of A. nubivena in South Australia and northwestern Victoria, shown by the heavy circled line, is from Moulds (1990, 2012), and marks the known distribution prior to this work. The dotted lines are roads. The dashed lines are State boundaries. The dot-dash line shows the approximate boundary of the ecoregion which defines the dominance of deserts and xeric shrublands within inland Australia (National Reserve System map, published by Australian Government). The filled arrows mark the locations of the audio recordings of A. nubivena illustrated in this paper. The hollow arrows show the locations of the audio recordings of A. fullo and A. pygmaea. The general locations of the major dunefields and other relevant areas noted in the text are labelled.

Figure 9. Comparative plots of amplitude spectra of: (A) Arenopsaltria pygmaea from 14 km northeast of Jurien Bay, Western Australia; (B) Arenopsaltria fullo, from Mullaloo Beach, north of Perth, Western Australia; (C–F) Arenopsaltria nubivena, from, respectively; 5.6 km west of Windorah, southwest Queensland; 72 km south of Cooper Creek crossing, Birdsville Track, Strzelecki Desert, South Australia; 105 km east southeast of Yulara, southern Northern Territory; and 18 km east of Eneabba, Western Australia, respectively. Note the weak extensions in all the plots to frequencies higher than the defined dominant frequency. The horizontal bars define the high amplitude frequency envelope of each spectrum, used to estimate the dominant frequency and the nominal bandwidth of each song. Each spectrum shown only between 3 to 16 kHz.

Terminology for timbals: LR1 to LR4, long ribs 1 to 4; SR, short (intercalary) ribs; TP, timbal plate. Terminology for pygofer: aed, aedeagus; as, anal styles; at, anal tube; bl, basal lobe of pygofer; bp, basal plate; db, dorsal beak; ds, distal shoulder; md, median lobe of uncus; sl, subapical lobe of uncus.

Figure 8 in Arenopsaltria nubivena (Cicadidae: Cicadinae: Cryptotympanini) from the Arid Regions of Central Australia and Southwest Western Australia
Figure 8. Arenopsaltria nubivena, higher resolution waveform and accompanying amplitude spectra plots of complete macrosyllables and segments of adjacent macrosyllables. The two recordings are of the calling songs, from 5.6 km west of Windorah, southwest Queensland. The macrosyllables each have six dominant syllables. A and C are waveform plots showing the high amplitude dominant syllables (labelled DS in A), these separated by smaller secondary syllables (labelled SS in A). Between these syllables are mostly low amplitude background pulses, possibly reverberation induced. The results of measurements on the carrier wave pulses are shown above the waveforms, showing the limits and calculated frequency (in kHz) within each of the short song segments, these mostly corresponding to the syllables and background pulses. B and D are the respective amplitude spectra of each of the two waveforms shown in A and C. The numbers adjacent to the selected spectral peaks are kHz. The measured frequency ranges (horizontal lines) and weighted mean frequency (downward pointing arrows), which are derived from the waveform plots, are shown. Song recordings filtered to 1 kHz.
