NEW HORIZONS
      LORRI KEM1
      CALIBRATED V2.0

This data set contains Calibrated data taken by the New Horizons Long Range Reconnaissance Imager instrument during the KEM1 ENCOUNTER mission phase. This is VERSION 2.0 of this data set. This data set contains data acquired by the spacecraft between 08/14/2018 and 01/31/2019. It only includes data downlinked before 02/01/2019. Future datasets may include more data acquired by the spacecraft after 08/13/2018 but downlinked after 01/31/2019. It includes a number of distant Kuiper Belt Objects (DKBOs). It also includes images of the approach field where MU69 was expected to reside during the MU69 encounter on Jan. 1, 2019. The data also covers the actual MU69 encounter.

ULYSSES JUPITER SOLAR CORONA EXPER. RANGING DATA 10 MIN AVG

The Ulysses spacecraft was occulted by the Io Plasma Torus (IPT) during its Jupiter encounter on 8 February 1992. The Ulysses dual-frequency radio subsystem used by the Ulysses Solar Corona Experiment (SCE) was utilized to measure the electron content (column density) of the IPT [BIRDETAL1992B]. In the nominal mode for radio-sounding observations [BIRDETAL1992A], both downlinks (S-band: f_s = 2.3 GHz X-band: f_x = 8.4 GHz) are phase coherent with the uplink (S-band: f_u = 2.1 GHz). The dual-frequency radio-sounding technique exploits the dispersive nature of ionized media on the propagation of the two downlinks. The tiny Doppler shift due to plasma moving in and out of the ray path is greater at S-band than at the higher frequency X-band.

Global Fertilizer and Manure, Version 1: Nitrogen in Manure Production

The Nitrogen in Manure Production data set of the Global Fertilizer and Manure, Version 1 Data Collection represents the amount of nitrogen manure produced and present on the landscape. The manure production at grid cell level was computed based on livestock population and nutrient excretion rates. The livestock population per grid cell was computed by multiplying the density values from FAO Gridded Livestock of the World by the area of grid cell. Spatially explicit manure produced and present on landscape is derived by combining the number of livestock heads and the nutrient excretion rate. The data were compiled by Potter et al. (2010) and are distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).
