warn_icon.gif IMPORTANT MESSAGE Sep 23, 2016    OCO-2 Resumes Data Delivery   

OCO-2 Project resumed delivery of calibrated radiances and science retrievals data for archive and distribution at GES DISC, starting with Data Day September 20, 2016. After experiencing anomaly on August 10, and  re-powering on August 14, the instrument had to go through a lengthy decontamination and calibration cycle.  There will exist permanent gap in science data between August 11-20, 2016. Users should be aware that data in the following period, August 21 - September 15, 2016, will be retrospectively processed into version 7r, but it were collected while the calibrator door position was offset.

The A-Train Data Depot (ATDD) has been developed to process, archive, allow access to, visualize, analyze and correlate distributed atmospheric measurements from A-Train instruments.  The ATDD portal provides easy on-line data access and services for science, applications, and educational use so that users get exactly the data they want, and not large files of data which would take much time and effort by individuals to be co-registered and refined.

 

Choi-wan Snapshot from GoogleEarth

On September 15, 2009, the A-Train formation happened to fly over the super-typhoon Choi-wan. Just one such event can yield enormous amounts of data of various science content and format from the diverse A-Train sensors.  Plotting quickly  retrievals like cloud profiles, cloud top temperatures, rain rates,  water vapor content, etc.,  for head-to-head previews, is the strength of the Giovanni  web tool. An example of the  tool output is shown on the left. Apart from these 2-dimensional plots, Giovanni provides KMZ (GoogleEarth) format of the vertical atmospheric profiles (far left). Thus, it is now possible to combine horizontal and vertical data layers in one three-dimensional object, and preview data from different geometrical aspects. The far left plate shows a snapshot from a GoogleEarth KMZ file where CloudSat profiles are pictured together with MODIS/Aqua true-color image, and AMSR-E rain rate.
