Hi Avi,<br>
<br>
The procedure we use to release data is discussed here:<br>
<a href="http://gmao.gsfc.nasa.gov/research/merra/faq.php" target="_blank">http://gmao.gsfc.nasa.gov/research/merra/faq.php</a><br>
<br>
question 1, on the FAQ list :-) However, in reviewing that, I think<br>
it's become dated. The near real time data are intended to be<br>
processed within two weeks of the end of a month. After that, data and<br>
automated quality checks are reviewed for problems. In January, we did<br>
have to hold data for apparent problems during the processing.<br>
<br>
In going back through emails, February data was released by the GMAO<br>
on Mar 19. After which, the GES DISC registers the data on their<br>
servers. While it all takes some time, and the people who are doing<br>
it have other tasks as well. This is a stable way to routinely update<br>
the data, and ensure we are not posting data with problems. While<br>
problems are rare, its best to look at the data before releasing to<br>
the community.<br>
<br>
Thanks for your interest in MERRA. Oh, and I notice that you are<br>
computing monthly means, and wanted to be sure you know that we have<br>
precomputed monthly averages on hat server. While there are many<br>
reasons to do this for yourself, if you just need monthlies, then<br>
using the precomputed data would be more efficient.<br>
<br>
