Re: Is there a guide for using CALIPSO data?

On Nov 17, 2015 The Data User’s Guide is an excellent overview of the CALIPSO project’s data: http://www-calipso.larc.nasa.gov/resources/calipso_users_guide/. Other recommended documents are the: Algorithm Theoretical Basis Documents (ATBD) (http://www-calipso.larc.nasa.gov/resources/project_docume...

Re: How are CALIPSO datasets organized?

On Oct 13, 2015

The datasets are stored as hdf files and are organized by processing level and sensor: with Level 1 being full resolution, time and geo-referenced instrument data, Level 2 being the derived geophysical variables, and Level 3 being the variables mapped on a uniform space-time grid.

Re: What are TOA and surface fluxes?

On Nov 17, 2015 The-Top-of-Atmosphere (TOA) layers are where the first interaction occurs as the radiation from the Sun reaches Earth and then the various atmospheric layers containing gases, clouds, aerosols, and/or other constituents before finally reaching the Surface. Solar radiation is scatter...

Re: EPIC and the Moon During Solar Eclipses

On Aug 17, 2017 the DSCOVR Team posted

The angle between EPIC and the Sun on March 9th 2016 is 8.78 degrees. If we see the shadow, we cannot see the moon. Note that the angular size of the Earth is around 0.5 degrees.

The original per-band images are in the level 1B EPIC products. They need to download the HDF 5 products stored on the ASDC/Earthdata website and use an HDF reader to view the images.

Re: Instrument Characteristics

On May 09, 2017 Roger Davies, the author of the study, posted “There is no ‘agenda' in making or interpreting the cloud height observations. The very careful analysis of the observations clearly shows that the short term (i.e. 15 year) record of cloud heights is dominated by El Niño and La Niña flu...

Re: Question About SRB SW Flux Products

On Mar 08, 2017 Stephen Cox posted

We do account for energy past 4 microns by putting it into the solar output in the last band we use, which is 0.7-4.0 microns. The result for SRB Release 3.0 is a Total Solar Irradiance of 1367 W/m2.

Re: TES Ozone L3 data

On Jan 06, 2017 Ming Luo posted

TES L3 data are generated when the Global Survey (GS) data are available. See the data calendar on this page, http://tes.jpl.nasa.gov/data/datacalendar/. There is no GS data taken post 2012. You should use TES L2 data for the study that you described.
