Re: v002 delays and incomplete updates VJ113A1 VNP13A1

We checked and for the VNP13A1 and VJ113A1 for June 17, 2024 the tiles you asked about are all available. Full suite of products were generated on July 3, 2024. The VI (VNP13A1/VJ113A1) is a 16-day product, so the outputs are not created until 16-days (give or take a little) from the start time of t...

Re: MOD06_L2 data ranges and missing data

Our product SME investigated MOD06_L2 data and found how to distinguish Cloud_Optical_Thickness (COT) between no data case and failed retrieval. For example, for 2.1 micron (band 7), the valid range for scaled Cloud_Optical_Thickness (1354, 2030) is [0,150]. The valid range for scaled Retrieval_Fail...

Re: MOD06_L2 data ranges and missing data

Yes, the scale and the add_offset are fixed for each Scientific Data Set (SDS). The following conversion equation should be used to convert stored integers back to useful floating point values: float_value = scale_factor * (integer_value – add_offset) Information about missing data is provided in th...

Re: VNP46A2 - VIIRS/NPP Gap-Filled Lunar BRDF-Adjusted Nighttime Lights Daily Extended GAP

Yes, you are correct, the data gap and delay in processing is because of the impact of the GPS Anomaly posted on the forum and at: https://ladsweb.modaps.eosdis.nasa.gov/alerts-and-issues/143045 We should be able to resume the C1 processing and take it up from that day on wards, but will not get pro...

Re: CLDPROP_L2_MODIS_Aqua data missing?

Is there a specific file that you are referring to because we checked CLDPROP_L2_MODIS_Aqua.A2005001.0000.011.2021144065133.nc file and it seems complete with all SDSs in it (see attached)

Re: APIv2: TemporalRange across years giving strange results

Thanks very much for notifying this issue. Yes, seems to be a bug. We will try to get to it soon, however due to current priorities it might take several weeks before this gets resolved. We are expecting that the earliest we can get to it is around middle of July.
