+### About HARP2
+The Hyper-Angular Rainbow Polarimeter #2 (HARP2) instrument, flying aboard the PACE spacecraft, is a wide-angle imaging polarimeter designed to measure aerosol particles and clouds, as well as properties of land and water surfaces. The amount and type of particles in suspension in the atmosphere are relevant to applications pertaining to health effects, cloud life cycle and precipitation, climate, etc. HARP2 will combine data from multiple along-track viewing angles (up to 60 degrees), four spectral bands in the visible and near infrared ranges, and three angles of linear polarization to measure the microphysical properties of the atmospheric particles including their size distribution, amount, refractive indices and particle shape.

+### About PACE
+[PACE](https://pace.gsfc.nasa.gov/) is NASA's Plankton, Aerosol, Cloud, ocean Ecosystem mission. The mission carries the Ocean Color Instrument (OCI), the Spectro-Polarimeter for Planetary Exploration (SPEXone), and the Hyper Angular Research Polarimeter (HARP2). OCI, PACE’s primary instrument, is an optical spectrometer that measures the intensity of light over portions of the electromagnetic spectrum. SPEXone and HARP2 are multi-angle polarimeters and they will be used to measure how the oscillation of sunlight within a geometric plane - known as its polarization - is changed by passing through clouds, aerosols, and the ocean. Measuring polarization states of UV-to-shortwave light at various angles provides detailed information on the atmosphere and ocean, such as particle size and composition. PACE will cover the entire globe every two days.

 The image is applied with a divergent blue-green to brown color palette. It depicts areas with a lot of green leaf growth, indicating the presence of chlorophyll, in dark green colors. Chlorophyll reflects more infrared light and less visible light. Areas with some green leaf growth are in light yellows, and areas with little to no vegetation growth are in shades of brown.

+The OPERA Radiometric Terrain Corrected SAR Backscatter from Sentinel-1 (RTC-S1) is a Level-2 (L2) product. It provides terrain-corrected radar images with a 30-meter pixel spacing and a temporal resolution of a few days to weeks on average, depending on the location. Each RTC-S1 product is derived from a Sentinel-1 Interferometric Wide (IW) Single-Look Complex (SLC) burst, provided by the European Space Agency (ESA). Synthetic aperture radar (SAR) images deliver all-weather, day-and-night, imaging of the Earth’s surface.
+
+RTC-S1 images are displayed in false-color for better visual interpretation of the SAR backscatter data. The false-color RGB visualization combines both co-polarized VV (vertical transmit vertical receive) or HH (horizontal transmit horizontal receive) backscatter values (red and blue) with cross-polarized VH or HV values (green) to generate a color image from SAR data. In this false-color scale, vegetated areas appear green; urban and/or sparsely vegetated areas appear white/pink; calm water, dry sand, and frozen ground appears black; and rough water appears purple or magenta. Note there are other land covers not listed that may have similar appearance and it is recommended that users consult auxiliary datasets to help determine the land cover of interest.
+
+The OPERA RTC-S1 product contains modified Copernicus Sentinel data corresponding to the same time period of the OPERA RTC-S1 product. The organizations in charge of the OPERA project and the Copernicus programme by law or by delegation do not assume any legal responsibility or liability, whether express or implied, arising from the use of this product. Users, including those who redistribute, adapt, modify, or combine RTC-S1 data, must comply with the terms of the [Copernicus Sentinel Data License Agreement](https://www.earthdata.nasa.gov/engage/open-data-services-software/end-user-license-agreements#toc-sentinel-1-end-user-license-agreement).
+
+ The OPERA RTC-S1 product is produced by the Observational Products for End-Users from Remote Sensing Analysis (OPERA) project. The OPERA project, managed by the Jet Propulsion Laboratory and funded by the Satellite Needs Working Group (SNWG), creates remote sensing products to address Earth observation needs across U.S. civilian federal agencies.

 The Ocean Color Instrument (OCI) is a spectrometer used to measure intensity of light over portions of the electromagnetic spectrum: ultraviolet (UV), visible, near infrared, and several shortwave infrared bands. It will enable continuous measurement of light at finer wavelength resolution than previous NASA ocean color sensors, providing detailed information on the global ocean. The color of the ocean is determined by the interaction of sunlight with substances or particles present in seawater such as chlorophyll, a green photosynthetic pigment found in phytoplankton and land plants.
