Re: Delay in VNP09A1 and VJ109A1 Products

Hello, @dgolon I'm really sorry about the trouble, but I'm not being able to get the same results as you are. Just so we can have the same reference point, if you access this link: https://search.earthdata.nasa.gov/search/granules?p=C2519124793-LPCLOUD&pg[0][v]=f&pg[0][gsk]=-start_date&q...

Re: Delay in VNP09A1 and VJ109A1 Products

Thanks for the update, @dgolon!

VJ109A1 and VJ109H1 have indeed been updated, however VNP09A1 and VNP09H1 are yet missing the 2025-06-26 update.

Delay in VNP09A1 and VJ109A1 Products

Hi everyone, I'm reaching out to ask about the current delay in the VIIRS surface reflectance products—specifically VNP09A1 and VJ109A1. I noticed that: MOD09A1 and MYD09A1 are already updated through 2025-06-26, VNP09A1 is missing the 2025-06-26 data (latest available: 2025-06-18), VJ109A1 hasn't b...

MOD09A1/MYD09A1 Granules Missing from Earthdata but Available in Data Pool

Hi, I usually consume the MODIS surface reflectance products (MOD09A1 and MYD09A1). Currently, I have implementations for two download pipelines: via HTTPS requests to the Data Pool and via Earthdata. Since MODIS products are being retired from the Data Pool starting today, I’ve already been using t...

Difference in Data Availability Timing between MODIS and VIIRS Products (MOD09A1/MYD09A1 vs VNP09A1/VJ109A1)

Hi everyone, I have a question regarding the availability timing of MODIS and VIIRS products. Both MOD09A1/MYD09A1 (MODIS) and VNP09A1/VJ109A1 (VIIRS) are 8-day composite products based on similar acquisition periods. However, I’ve noticed that MODIS products are generally made available more quickl...

Re: Delays in MOD09A1 and MYD09A1 products.

Hello @dgolon, could you please confirm whether all granules for the date 2025-05-01 are already available in the data pool? Currently, I only see the following tiles for both MOD09A1 and MYD09A1 products: * h11v01, h14v15, and h24v01. Just wanted to check if this is the full set for that date (i.e....

Re: Delays in MOD09A1 and MYD09A1 products.

Hello @dgolon, My pleasure — I really appreciate you and the team resolving the issue so quickly. I've also made changes to my script to use the AppEEARS application, but I haven’t fully transitioned yet since the Data Pool is still functional. Thanks as well for the heads-up on the upcoming changes...

Delays in MOD09A1 and MYD09A1 products.

Why are MOD09A1 and MYD09A1 products delayed beyond 2025-04-23? I'm trying to understand the current delay in the availability of MOD09A1 and MYD09A1 surface reflectance products. According to the USGS FTP servers: MOD09A1.061: https://e4ftl01.cr.usgs.gov/MOLT/MOD09A1.061/?C=N;O=D MYD09A1.061: https...
