F I G U R E 5 in Global warming is projected to lead to increased freshwater growth potential and changes in pace of life in Atlantic salmon Salmo salar
F I G U R E 5 Ensemble average daily water temperature by day of year for the future projections under the three shared socioeconomic pathways and representative concentration pathways (SSP1-RCP2.6 left, SSP5-RCP7.0 middle, and SSP5-RCP8.5 right). Each line represents the day of year average temperature for the climate forcing ensemble with colors transitioning from blue to red toward the end of the century (starting with 2020 and ending with 2100). The lower dashed line represents the lower growth threshold temperature of 7 C, and the upper dashed line represents the upper growth threshold temperature for 23 C (Elliott & Hurley, 1997).

Chang'e 5 Lunar Ascent
<p>The ascent from the lunar surface of the Chinese Chang'e 5 lunar sample return mission was observed by radio. This dataset presents a recording of the X-band radio signal of the Chang'e 5 ascent module, which transmits at 8463.75 MHz. These recording were obtained from Roberts Creek, Canada, at latitude 49.4348N deg, longitude 123.668W deg, height 40 m. The ascent from the lunar surface occurred at 2020-12-03T15:10:24, data from the ascent module sitting on the lunar surface starts the recordings.</p> <p>A 66 cm parabolic dish was used to receive the X-band transmissions. System performance is estimated to be 66 cm @ 50% illumination at 8.43 GHz is 32.3 dBi. 136K is 21.3 dBK. G/T = +11 dB/K. approximately.</p> <p>The ‘gqrx_20201203_150513_8463750000_200000_fc.raw’ dataset consists of complex sampled (IQ) 32 bit floating point values (interleaved real/imaginary), sampled at 2 Msps at a centre frequency of 8463.75 MHz. This dataset begins at 2020-12-03T15:05:13 UTC. The RF system was locked to a GPS disciplined oscillator. NOTE: near the end of this data set there is a brief period where the receiver is knocked off frequency that can be seen in the step divergence from the trend in the data. The receiver is re-tuned to proper tuning and the trend can be seen to continue.</p> <p>The second data set ‘2020-12-03_ce5_lunar_launch.zip’ is dynamic spectra of signal recorded on a different receiver connected to the same RF path is also provided. These are averaged to 100Hz frequency resolution and 1 second time resolution and stored as 32 bit floating point values. Each spectrum of 20000 channels is preceded by a human readable header of 256 bytes, providing metadata. No discontinuities are known in the second dataset. Timestamps in UTC are embedded in the file.</p>
Chang'e 5 RF recording at 8471.2 MHz with Allen Telescope Array during LOI-2
<p>This dataset contains a recording of X-band telemetry signals from the Chinese lunar sample retrieve mission Chang'e 5 done on 2020-11-29 before and during the LOI-2 (lunar orbit injection 2) manoeuvre that circularized the spacecraft's elliptical lunar orbit. The recording was done at Allen Telescope Array using antenna 1h in dual XY (linear) polarization.</p> <p>The hardware configuration was as follows: antenna 1h was connected to RFCB LO d, which was tuned to a frequency of 8475 MHz and used an output IF of 512 MHz. A USRP N321 was connected to the IF output of the RFCB and digitized both polarizations. The USRP used external 10 MHz reference and PPS coming from the observatory distribution system. The IQ sample rate of the USRP was 30.72 Msps and a GNU Radio flowgraph was used to channelize four frequencies from the spacecraft (8463.7, 8471.2, 8478.6 and 8486.2 MHz), using an IQ sample rate of 240 ksps for each channel.</p> <p>The GNU Radio flowgraph stored the IQ data for each channel as 32-bit floats in the <a href="https://wiki.gnuradio.org/index.php/Metadata_Information">GNU Radio metatata file format</a>, with detached headers. After recording, the data was converted to <a href="https://github.com/gnuradio/SigMF">SigMF</a> format.</p> <p>This dataset contains the IQ data for the channel at 8471.2 MHz, which corresponds to the orbiter, in SigMF format. Each polarization is in a different file. The original metadata headers are also provided.</p> <p><strong>Note:</strong> during the observation, the frequency of the RFCB LO was lowered by exactly 30 kHz in two occasions to prevent the signals from drifting out of the channel passband due to Doppler. The two LO jumps can be easily seen in the residual carrier of the signals and corrected.</p>

The recording was done at Allen Telescope Array using antenna 2h in dual XY (linear) polarization.</p> <p>The hardware configuration was as follows: antenna 2h was connected to RFCB LO d, which was tuned to a frequency of 8475 MHz and used an output IF of 512 MHz. A USRP N321 was connected to the IF output of the RFCB and digitized both polarizations. The USRP used external 10 MHz reference and PPS coming from the observatory distribution system. The IQ sample rate of the USRP was 30.72 Msps and a GNU Radio flowgraph was used to channelize four frequencies from the spacecraft (8463.7, 8471.2, 8478.6 and 8486.2 MHz), using an IQ sample rate of 480 ksps for each channel. Only the 8471.2 MHz and 8486.2 MHz channels contains signals from the spacecraft.</p> <p>The GNU Radio flowgraph stored the IQ data for each channel as 32-bit floats in the <a href="https://wiki.gnuradio.org/index.php/Metadata_Information">GNU Radio metatata file format</a>, with detached headers. After recording, the data was converted 16-bit integers and <a href="https://github.com/gnuradio/SigMF">SigMF</a> format.</p> <p>This dataset contains the IQ data for the channel at 8486.2 MHz, in SigMF format. Each polarization is in a different file. The original metadata headers are also provided. This dataset contains the X polarization. The Y polarization can be found in "<a href="https://zenodo.org/record/4405177">Chang'e 5 RF recording at 8486.2 MHz with Allen Telescope Array on 2020-12-19 (Y polarization)</a>".</p>
