Portable Field Emission Spectrometer (PFES) data were acquired on July 15 and 17, 1989. A total of 31 measurements were collected for GRSFE. Of these measurements, 13 were calibrations and 18 were of representative surfaces. The data were collected primarily to support the calibration of the TIMS data and to assist in interpreting spectral mixing in the mid-infrared. Sites were selected for calibration that covered a range of emissivities. On July 15, PFES data were collected at Kelso Dunes and the Cima Volcanic Field as part of the Calibration Team effort. Daedalus and SIRIS data were collected over the same sites. For the PFES data, the Kelso Dunes Bright Target site represented the silica-rich endmember and the Cima basalt tephra Dark Target site represented the more silica-poor endmember. On July 17, PFES data were collected at two of the modelling sites at Lunar Lake (the playa and the cobble sites). Several spectra were also collected at the playa surface next to the Lunar Lake thermistor site.
